Can you tell me how to input my W-2's?

Go to Federal>Wages and Income to enter your W-2's.  If you have more than one, after you enter the first one, click Add W-2.  If it is a joint return, make sure you assign each W-2 under the correct spouse's name.

You might be able to import W2.  How to import or enter your W2,
