The idea is there in embryo, without being fully defined, much like the doctrine of the Trinity, the Eschaton, and even the clear-cut Table of Contents of the Canonical collection of the Bible itself.
As for purgatory, I said, not that it is explicitly named, proved, and fully defined, but that it is consistent with what the Bible teaches about three things:
This requiting, refining, and effective spiritual sharing is all about how He deals --- not with the lost souls, the damned--- but with His children -- according to Scripture. In God's great mercy, I hope that's every one of us.
This is very similar to the Immaculate Conception. There isn't a single bit of Scripture to support the IC, yet Roman Catholics continue to do so.
You're now admitting about indulgences and purgatory what Christians have said about them all long....they're not supported in Scripture.
To "see" this in the NT you have to practice eisegesis.....reading something into the text that isn't there.
And then you resort to a pitiful Tim Staples apologetic and not the Table of Contents isn't proved in the Bible.
When the Roman Catholic trots that line out, they've completely lost the argument.

Never found in the NT.
Never taught by an Apostle.
Totally pagan.
Yet you try to defend it by spinning.
