Retirement tax questions

When I run the federal check I get an error about this. W-2 box 12 code S should not be greater than the value in box 12 with code S for this W-2. Box 13 in my W-2 is checked for retirement plan.

 

When I click to correct, it shows me the amount from my W-2 and also shows me part of a form where it has letter S but both have the same amount. I don't understand what needs to be changed. Is it related to this same issue?
