If you worked as an employee and the employer used the option to reduce SS taxes on your paycheck in 2020 and you did not work for them in 2021 then it is NOT your responsibility to repay the reduced taxes voluntarily ... it is the employer's responsibility to pay them on your behalf then try to collect them from you. Contact the employer for directions on this matter as it cannot be done on the 2020 or 2021 return.
