@JoeLes I don't think that would work for me. I have a Form 2210 because without its annualized income installment method, TT reduces my refund (1040, line 34) by $70, the penalty amount. Using the annualized income method (I had a Roth conversion in December) correctly makes my penalty zero, but I have to fill out Form 2210 to document this. TT's Form 2210 with input by me does make the penalty go away, it's just that it's missing 2020 o/p credit which on parts of the form make it look like I did have an underpayment.
