In addition to what DoninGA and Scruffy_Curmudgeon said, you cannot file your tax return until you have all your W-2s, 1099s, and other tax documents. Many of these are not sent to you until the end of January or early February. Don't try to guess what will be on them. If you guess wrong, which is very common, and the numbers on the tax return that you filed don't match the actual forms, you will have a problem. Wait until you get the forms.
