If you filed before the $10,200 unemployment exclusion, the IRS will recalculate your return for you. There is no need for taxpayers to file an amended return unless the calculations make the taxpayer newly eligible for additional federal credits and deductions not already included on the original tax return.

At first Turbo Tax adjusted the filed returns for it. But only in your Turbo Tax account (it wasn’t sent to the IRS). BUT judging by posts I'm seeing it seems Turbo Tax put the returns back to the original filed one. Which is probably a good thing to match what was actually filed.
