Turbo tax reports one error found during Smart Check but nothing is actually shown as error

I've been having this problem, and I am not sure what is going on. This is TT Desktop 2023.

 

I run smart check, it says it found one error with my federal return and we will handle it one at a time, when I press continue, it says "your return has changed", it does not display any error, next step is done or run smart check again.

 

If I got to forms, and click the errors button, it says all is good.

 

Any idea of how to determine what is actually wrong?
