Actually, I did give answer "where" it was prohibited, which is what was asked.
It's plain enough to me that for whatever reason, you won't accept it. But instead try to rhetorically "finesse" one's way around the plain fact that the Roman church teaches all manner of things not much supported by Scripture, even frequently to the contrary of Scripture, and the Gospel as related to us all by the words attributed to Christ, testified to by the Apostles, then later much expounded upon by the likes of Paul.
Otherwise, In spite of my own explanations, in my own words, you attempt to tell me "what I believe" (is the Roman Catholic doctrine of Purgatory) so as to argue against that position.
Sorry mister, I won't play along with that game. That's part of the old 'drag it off into the bushes' routine, as far as I can tell.
Try again if you wish, but I think we are done here.
Yet ask yourself this;
You may spare both yourself & myself the misery of reading through some version of the Roman religious system "answer", to that question (if there is one) if you wish. By all means do not feel yourself obliged to explain such to ME.
Paul wrote to the church at Roman because many were trying to “earn their way” to heaven. He reminded them of their pride in how “spiritual” they were, and made it clear that they were WRONG about their views. They haven’t changed much... but now they have lots of gold and a fellow in a funny hat telling them he speaks for God...
Joseph Smith had Urim and Thummin, Rome has special categories of “saints” and pray to Jesus mother in order to get God’s ear...
Not much different, but at least the RCC doesn’t have magic underwear!

I see God’s grace as a sort of “umbrella”. When we become His, His Blood covers ALL OUR SIN (past and present), and all He sees is that covering umbrella! When we acknowledge His Lordship, He begins the process by giving us the Holy Spirit as our guide! Do we continue to sin...? Yes, but He will help us overcome it, through OUR faith!
2Timothy 1:12 That is why I am suffering as I am. Yet I am not ashamed, because I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him for that day.

Romans 4:1 — What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter? 2 If, in fact, Abraham was justified by works, he had something to boast about—but not before God. 3 What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.”[a]
4 Now to the one who works, wages are not credited as a gift but as an obligation. 5 However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness. 6 David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works:
7 “Blessed are those
whose transgressions are forgiven,
whose sins are covered.
8 Blessed is the one
whose sin the Lord will never count against them.” ....

... Romans 5: 6 You see, at just the right time, when we were still powerless, Christ died for the ungodly. 7 Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. 8 But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
9 Since we have now been justified by his blood, how much more shall we be saved from God’s wrath through him! 10 For if, while we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! 11 Not only is this so, but we also boast in God through our Lord Jesus Christ, through whom we have now received reconciliation. ...

... 14 We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15 I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16 And if I do what I do not want to do, I agree that the law is good. 17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature.[c] For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
21 So I find this law at work: Although I want to do good, evil is right there with me. 22 For in my inner being I delight in God’s law; 23 but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. 24 What a wretched man I am! Who will rescue me from this body that is subject to death? 25 Thanks be to God, who delivers me through Jesus Christ our Lord!
You misunderstood what the "it" in the question is. Rather typical of all Protestant sects, to defend their heresies with quotes that do not support them, and ignore the quotes that condemn them. The cure for Protestantism is simple: read the Holy Bible every once in a while and attempt to understand what you are reading.
the Roman church teaches all manner of things not much supported by Scripture, even frequently to the contrary of Scripture
No, not "contrary", in the doctrinal part. In manners of discipline, yes, disciplines changed since the 1c. If you believe otherwise, give me an example. If you want to drop this topic, you have a right to do so, of course, on the thread about Purgatory. However, the question was, where does the scripture condemns teaching on the subject not covered by the scripture. Useful meaning-of-words hint: when something contradicts the scripture that means the scripture covers it.
What sins are NOT covered by the blood of Jesus?
Every single one of them is redeemed by the blood of Christ, of course. That is somehow related to the issue of Purgatory? Those in purgatory are there because of the redemption wrought by Christ. If you do not understand that, you do not understand either the Purgatory or the mission of Christ.
