IRA Cost Basis for nondeductible contributions

When I completed the TT interview I mistakenly did not accept the nondeductible IRA cost basis figure that TT showed that had been carried forward from previous years. Now I need to go back and hopefully find and accept the IRA cost basis figure that I unfortunately changed.

 

I've considered deleting and re-adding the 1099R in hopes that would trigger that IRA cost basis question but I am afraid to do thinking I might cause more problems.

 

I have gone back and cannot find that question in the interview. What is the best way to correct this mistake I made?

 

I would greatly appreciate and advice.


Than you kindly.
