"Also and[sic] non deductible can only be reported on a 8606 for the tax year that the contribution was for."
The idea is to put the total prior years basis on the current Form 8606.
You don't need an amount on line 1 to enter an amount on line 2.
I've always argued to put the missing total prior years basis on the current year form 8606 and
send in one form attached to your tax return, and be done with it.
I get a lot of pushback here on that suggestion.
Use your own judgement.
"Is is[sic] the dollar amount of contributions that were nondeductible?"
It is the total amount of contributions for which you did not take a deduction.
