The recharacterization in 2021 of a Roth IRA contribution for 2020 to be a traditional IRA contribution instead could result in either a deductible contribution or a nondeductible contribution depending on your 2020 modified AGI and participation in an employer-provided retirement plan in 2020. If that contribution was nondeductible, your 2020 tax return should have included Form 8606 reporting that nondeductible contribution and would have resulted in basis shown on line 14 that would carry forward to line 2 of your 2021 Form 8606 to be used in calculating the taxable amount of any Roth conversions that you did in 2021.
