How to correct history of old Roth contributions in TurboTax Deluxe

[lesmikesell]

I have an incorrect amount for a Roth contribution that has been carried forward many years in TurboTax Deluxe, and a couple of years where it was not entered.   These do not affect the filed taxes but I'd like the history to be correct and I can only see where to enter the current year's number.  How do I find and change those old values?

You can send in a Form 1040X with a corrected Form 8606 to correct your Roth IRA basis.
