If you had no income for this employer do not enter it on your return.

If you feel that there is an error on your W-2 contact your employer.

If this is a corrected W-2 :

It sounds like it might be a corrected W-2 that they only changed the boxes that changed from the original W-2.   If that is the case and the SS and Medicare are different from the original W-2 then you would enter the information from the original W-2 and replace the SS & MC with the new updated information.   

The employer should have issued a total new W-2C (corrected) to totally replace the original but some employers only send the boxes that changed and expect you to update only those boxes.   Check with your employer.
