How to do backdoor Roth IRA conversion for TY 2021 in 2022?

Please see the instructions below they include steps on how to enter a basis from a previous year.

 

To enter the nondeductible contribution to the traditional IRA for 2021 on your 2021 tax return:

 

1. Login to your TurboTax Account 
2. Click on "Search" on the top right and type “IRA contributions” 
3. Click on “Jump to IRA contributions"
4. Select “traditional IRA”
5. Answer “No” to “Is This a Repayment of a Retirement Distribution?”
6. Enter the amount you contributed
7. Answer “No” to the recharacterized question on the “Did You Change Your Mind?” screen
8. Answer the next questions until you get to “Any Nondeductible Contributions to Your IRA?” and select “Yes” if you had a nondeductible contribution before this tax year.
9. If you had a basis in the Traditional IRA before then enter the amount.
10. On the “Choose Not to Deduct IRA Contributions” screen choose “Yes, make part of my IRA contribution nondeductible” and enter the amount (if you have a retirement plan at work and are over the income limit it will be nondeductible automatically and you only get a warning and then a screen saying $0 is deductible).

 

 

TurboTax will create Form 8606 with a basis on line 14 to carry over to 2022 (enter on your 2022 tax return).
