do you have a spouse and you accidentally clicked that the W-2 was your's and not the spouses? this is common errors people make.
overpaying FICA could occur if you had more than one employer and your Box 3 wages on your W-2s sum to more than $132,900
if your wages are below $132,900, something else is incorrect.
if you truly overpaid FICA, it will be calculated into your refund. Nothing for you to do.
