I have a client whose Box 3 and 5 amounts are both $225389.99 on a single W-2 (the result of a mid-year merger so not a typo).  SS Tax withheld in Box 4 is $13974.73.  Proseries Professional is NOT applying the excess the Schedule 3 Line 11 as an overpayment.  I tried splitting the W-2 into 2 entries but no joy.  Interestingly when I change the EIN on the second entry it works.  But of course I can't file that way.

Any ideas??
