After you file

@fanfare 

You were correct in your assessment. I failed to enter the value of my traditional IRA as of December 31, 2022. I have now used Turbotax to do an amended return based on correctly entering the requested data from Form 1099-R. This has resulted in a change to my adjusted gross income, as expected, but Form 8606 was not updated to reflect the correct traditional IRA value. Is there a way, using Turbotax, to get Form 8606 updated?
