Just take things once step at a time :
1. I made a $6k after-tax contribution to my traditional IRA in Dec 2020. Reported on the 2020 return as non deductible contributions.
2. I then converted $6k from my traditional IRA to a Roth IRA in Jan 2021.
3. I made another $6k after-tax contribution to my traditional IRA in Dec 2021.
2&3 are both reported on the 2021 return ... first enter the 2021 non deductible contribution and then enter the issued 1099-R and simply follow the program screens to indicate the conversion.
4. Lastly, I converted $6k from my traditional IRA to a Roth IRA in Jan 2022. Easy ... using the issued 1099-R you will report this on the 2022 return.
