I think I have a similar problem:
I am filing an amended return for 2021 -- adding in an omitted bank interest payment.
This means that I will owe some money. The 1040-X reflects this properly, but I basically have to subtract out the omitted bank interest payment on the Form 8888 to get TurboTax to let things slide. But this seems to be moving in the wrong direction, since the last thing I want at this point is for the IRS to refund me more money.
I have to submit on paper. Am I okay to just ignore the Form 8888 reconciliation in TurboTax and not send that along when I send in the amended return 1040-X with revised 1040?
