Last year, I was working as F1 in OPT. As F1, I can exempt from society security tax and medicare tax. But the accounting company also exempted my Federal tax and told me that was the way to do it. I thought I could report my Federal tax later, so I let it go. But right now, I get my W-2. Surprising me, there is no Federal Wage reported in my W-2. All columns of Federal Filing Copy and NY. State Filing Copy left blank except state income tax item. :confused:

In this case, how can I report my Federal tax? I'm really appreciate if you could help me!
