Something similar is happening to me.
As an aside TurboTax makes it virtually impossible to send a question to Tech Support and their phone reps are useless.
Here's the situation in TurboTax Deluxe 2021 (desktop). I have interest from cashing US Savings Bonds. I have the 1099-INT and entered the amount manually and answered the questions that followed. Then the software counted that amount twice - doubled my actual interest. Makes a big difference in tax due and I can not correct it. This needs to go to Tech Support and programmers which I can't do.
Beware
