What is the amount on 2023 Schedule 1 Line 20.?
If you took a deduction you cannot also file Form 8606 showing that contribution.
Form 8606 can be filed only if
A) you made an IRA contribution for that year.
B) you are not eligible for a deduction or'
C0 you elected to make it non-deductible.
OR
D) you made non-deductible contributions in earlier years and you have a prior years basis showing on an earlier Form 8606 Line 14 and you did a Roth conversion.
Form 8606 alone will not reduce your tax, You must file an amendment for that with all new or changed forms attached.
