Get your taxes done using TurboTax

When the 1099-R interview asks if you tracked your basis and you say yes then if asks for prior years basis (non-deductible contributions) and you enter the last filed 8606 line 14 amount for the 8606 line 2 amount.   Nothing goes into the IRA contribution interview unless  you made a 2021 non-deductible contribution for 2021 which would apper on line 1 of the 8606.
