I got 2 w2s from the same employer

[shannonb1996]

One includes state tax and one doesn't they are about 300 dollars different in total. how do I know which one to use or do I use both?

You can enter both.

If you are still in the process of working on your return but need to get back to where you can enter an additional W-2:

1. Click on "Federal Taxes"
2. Go to "Wages & Income"
3. Click on "edit/add" next to your W2
4. Click on "add another W2"
   
   Hope this helps.
