I'm seeing the same "bad math" WRT to IRAs and information from 1099-R (Inherited IRA with RMD) + non-deductible Traditional IRA contributions. I thought I was losing my mind until I round this thread. TT indicated I was due a refund until I verified the numbers it has for the taxable and non-taxable parts of the 1099-R Inherited IRA with RMD and saw that 2020 TT is for some reason saying parts of that RMD are not taxable when every box on the 1099-R says taxable!
Digging further, I believe they are confusing when you have both an inherited IRA/1099-R with RMD AND you have made non-deductible contributions to a regular IRA with being tracked by TT. It's somehow really messing up the "taxable part of the RMD" which should be 100% taxable. It is also messing with the basis of the traditional IRAs and asking me (for the first time) the "value of all your traditional IRAs" on 12/31/2020. It's never, ever asked that before. Now when you enter those YE 2020 values, it really seems to get confused.
TT support needs to fix this promptly b/c non of us will be able to file.
I'm reviewing the posts above for more clues. THANKS so much for posting your same dilemma! Stay safe, stay alive! Peace.
