The 16th Amendment gave Congress NO NEW power to tax. The 16th Amendment income tax is an excise tax, limited to enumerated areas in Article I that the states gave Congress authority over. Therefore, if you are paying tax in earnings that are not associated with A1 excise activities, then it is you who are at fault for not informing yourself of the truth of the 16th Amendment.
You’re correct that the 16th gave no new power to tax. They always had the power to tax income, and so they did. Bad idea in my opinion, but my opinion doesn’t matter, it’s the law.
Are you a tax protester? You certainly sound like one.
XVI begins: "The Congress shall have power to lay and collect taxes on incomes..."
If this is not a grant of power to Congress, what is it?
