Its asking me to review my husbands W-2. He is on Social Security. He has no W-2. How do i change this under wages and income?

It's possible the W2 was carried over from last years return.  Regardless, if you do not have a W2 just delete it.  

It's easy to remove a W-2.

1. Open or continue your return.
2. Search for W-2 using the search in the upper right corner and then click the Jump to link in the search results.
3. This brings you to the Here's your W-2 info screen. Click the trash can icon next to the unwanted W-2 and then answer Yes on the following screen.

If he worked in the past, and you starting by importing last year's info, Turbotax created a blank W-2 for you to fill in.  If you don't need it, you can delete it.
