I had no federal income tax withheld this past year since we knew we would be able to claim the adoption tax credit and would be getting a refund.

On my W2 box 1 and 2 are empty. 3-5 are all filled out correctly. Shouldn't box 1 have my gross pay and box 2 be $0? My employer is saying that box 1 has to be empty since I had no federal income tax withheld. This doesn't seem correct to me, I had taxable income, just opted to have nothing withheld. Any insight?

Turbo tax won't let me input this W2 since box 1 is empty.
