So I did do a Roth conversion but never had any non-deductible content in the TIRA. I see the conversion in #3 and can only hope that assumes one may have a basis to calculate .. I do not. So, last years filing for 2020 was missing the 8606 but AGI and taxes due/paid are not changed. The only other anomaly is that the 1040-sr has line 4a blank and line 4b alone has the conversion amount. Do you think I'm okay to do nothing, should In send in an 8606 alone (with explanation), or in conjunction with a 1040-x. I feel it will become moot after the next filing .. repeating the same process WITH the TT generates 8606 .. still no basis. Perhaps I should fill out part 1 to make it perfectly clear that I have no basis ?
Thoughts ?
