Form 8606

Both my Federal and State tax returns have been filed and accepted.

 

It has now come to my attention that Form 8606 has an error. Line 6 of the form was left blank. It should have contained the value of my traditional IRA at the close of December 31, 2022. This information was accessible to Intuit turbotax so I don't understand why it wasn't properly entered on the form.

 

The Form 8606 error means that Form 1040-SR line 4b is incorrect. Consequently, the adjusted gross income is incorrect.

 

Since the Federal tax return has errors and since the State tax return requires a copy of the Federal return, the State return is also incorrect.

 

How is this conundrum to be fixed?
