I can not find where to add my and my wife's W2 information

To add a  W2 just type w2 (small W)  in the search box at the top of your return and click on Jump To the W2

OR  To Add a W2 enter it under

Federal Taxes on the left side

Then Wages and Salaries- Click the Start or Update button

Then if you are married you should have 2 buttons...Add w-2 for (taxpayer name) and Add w-2 for (spouse name). Click on the correct button to add a W-2.
