W2

If your employer withheld federal tax you will see it in box 2 of your W-2.   State tax withheld will show up in box 17.   Social Security and Medicare would also be shown on your W-2 but you do not get a refund for those.

 

If you think something is incorrect on your W-2, you need to ask your employer about it.

There is nothing on your W2 box 2?   Ask your employer about that.   

Are you saying the IRS garnished your paycheck to pay off previous years' taxes?

 

If that is the case, your W-2 will not show that amount.  Although the IRS should send you a statement showing how much they took out and how it was applied to your overdue tax.
