When you look at your Form 1040 (under Forms, second form listed on left), line 1 , if your wage amount on this line includes your foreign wages, that is all that the IRS really cares about. Just so the income is reported on your return. You can also look at the 1040 wks (worksheet) (first form on the list on the left) and review that form you should be able to see your foreign income entry. But the IRS does not mind if you have wage income that is not reported on a form.
