In 2021, my spouse and I each contributed $6000 to our Roth IRAs. Later, we learned that our 2021 combined income was too high for Roth contributions, so in early 2022 we recharacterized our contributions as traditional contributions. My spouse's recharacterized value was $6446, and my recharacterized value was $6174.
Later in 2022, we each used a backdoor Roth conversion to move this money into our respective Roth IRAs. At that time, the value of my spouse's conversion was $6120 and my conversion was $6169. All the money that we converted had been initially contributed in 2021 and recharacterized in early 2022 (our traditional IRAs had $0 in them at the beginning of 2022).
Later in 2022, I contributed $1500 to my traditional IRA, and my spouse contributed $4774. We did not do any more backdoor Roth conversions in 2022.
We received 1099-Rs for our recharacterization and our backdoor Roth conversions. The recharacterization 1099-Rs do not have a taxable amount, and the 1099-Rs from the backdoor Roth conversions have "Taxable Amount not determined" checked.
1) How much of the recharacterization/Roth conversion is taxable, and how do we correctly input this into Turbotax, given that the contributions were made in 2021, but the backdoor Roth conversion was done in 2022?
2) Do we need to file an amended Form 8606 for 2021?
Thank you very much.
