For W2 you fill out the first one it will have a new page at the end that comes up and asks if you have another to enter. If you start over, it should do exactly the same thing. So if you didn't find it, select Wages & Income' and step through the entries for your first one until you get to the end of it. The next page should have the question 'Do You Have Another W-2 to Enter? with a yes or no selection - select yes to get another W2 blank form. You will have to do that four times to get all four entered.
Once you have one of them entered I think that it allows you to add another on that window. It says Here is what you have so far and allows you to edit each one and to add others.
