Unpaid FICA Tax

Hi everyone,

My employer didn't withhold FICA taxes from January through March of 2023 due to me not realizing my residency status in the US changed from nonresident to resident alien. Starting in April of 2023, my employer did withhold the appropriate amount for the FICA tax.

The issue is that I'm not sure that I paid these taxes back when I filed my 2023 tax return. If I did, where to check that in my tax return for 2023? If not, which is likely what happened, how do I pay this back? If anyone has any advice and wouldn't mind sharing, I would really appreciate it.

(I'm also not sure if my employer needs to do anything regarding this on their part?)
