If you had two or more employers in 2020 and the total of all Social Security taxes withheld in box 4 of your W-2 is greater than $8,537.40, the excess SS taxes will be entered on your federal tax return Schedule 3 Line 10.
The total from Schedule 3 Part II flows to Form 1030 Line 31 as a tax payment.
The excess SS taxes withheld will be included in your federal tax refund or they will reduce the amount of federal taxes owed.
