Hold on. Do you have a 401k with your employer? That is not the same thing as a traditional IRA. If you have a plan with your employer it is most likely to be a 401k or 403b and is shown in box 12 (sometimes box 14) of your W-2. If you have that on your W-2 you do not enter it anywhere else. It is entered when you enter the information from the boxes on your W-2.
