Yes it is automatic. If you had more than 1 employer and paid more than $9,114.00 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.
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 $9,114.00. Even one penny over from rounding will be excess. So leave off the cents! Or post back with the amounts in boxes 3&4.
Check 1040 Schedule 3 line 10 for it. Then Schedule 3 goes to 1040 line 31
