In a nut shell... I did exactly as you say. The difference being that I imported the 1099-R forms for our accounts. Upon more careful examination of the related TurboTax forms, form 5329-S shows the $302 as being an excess contribution to her Roth IRA for 2020. This seems to be because line 10 of IRA Info Wks shows an excess contribution in 2019 of $302... supposedly from line 24 or her 2019 5329-S. But I looked at line 24 of the 2019 form, and it's blank. And, as far as I can tell, I can't edit line 10 of IRA Info Wks to correct the value. So... somehow, it seems that her 1099-R that shows the recharacterization was interpreted as replacing the value of her 2019 form 5329. I don't know how that's possible.
As the result... I'm going to assume this is a bug or mistake somewhere... possibly in the way I jumped from "Ask-me-everything" mode to "I'll-tell-you-what-I-want-to-enter" mode... and back. And, unfortunately, I'm going to start over.... with a clean slate to see if the values get entered the same.
A little while later.....
I've gotten past the 1099-R income part of the interview. I'm following the "Ask-me-everything" mode, which is a royal pain, since I don't have most of the stuff they're asking... but none the less... the IRA Info Wks now has a blank line 10 for both T and S columns. So... maybe there was an interview question I was supposed to answer, but because I didn't have TT "ask-me-everything" it never got a chance to ask me... and assumed something wrong. But... why would it show values that it has supposedly transferred from my 2019 taxes incorrectly?
