Let me back up. One thing schedule C line 11 goes to 1040 line 31 (not 18). Now, do you have more than 1 employer? Are you married? First make sure each W2 is assigned to the right spouse if married. The excess SS is for one person.
Is it saying you had too much SS taken out or that 1 employer took out too much? There are 2 different situations when it will say Employer may have paid too much Social Security. It’s saying either 1 employer took out too much SS –OR- that you paid too much SS because you had more than 1 employer.
For 2023, If you had more than 1 employer and paid more than $9,932.40 in Social Security tax (box 4) combined you get the excess back on your tax return. If you are married it is for each spouse separately. Be sure each W2 is assigned to the right spouse. For 2023 it will be on Schedule 3 line 11 which goes to 1040 line 31. The Social Security overpayment on line 31 is included in the total refund on line 35a or reduces a Tax Due on line 37.
Get a calculator and check each W2 box 3&4. Multiply box 3 x .062 and it should be box 4. The max for all box 4 combined (but only for each person) is $9,932.40. Even one penny over from rounding will be excess. So leave off the cents! Or post back with the amounts in boxes 3&4.
Or check W2 box 12. You may have entered Code A by mistake.
A sure way to fix this is to delete the W2 and re-enter it. That may clear something out.
