I missed contributing to my IRA in 2019, so in the early part of 2020 I made a 6k prior year(2019) contribution and 6k same year(2020) contribution to the same traditional IRA. I then used the backdoor process to convert the total 12k from my traditional to a Roth IRA. My 5498 shows a 12k distribution for 2020. All contributions were non-deductible. The traditional IRA had a zero balance at the beginning of 2020.
I've entered this data into TurboTax Desktop version, but I can't seem to figure out where to enter the 6k for the prior year(2019) contribution. All of the interview questions seem to skip the part where I added 6k in non-deductible basis for 2019, so I am getting taxed on that amount of the conversion. What am I missing?
