Missed small w-2 on eFile fed, add to mail in state?

[DarrenRadcliffe]

I missed a small W2 (only $750) on my federal. It was e-filed. I have MAIL in my State. Do I add it to state? Or submit state without? Then amend both? Or just amend federal?

No do not submit the incorrect state return.  Instead go ahead and go through the amend steps for your federal return.  This will update your state return so that your original file with them will be correct.  I recommend waiting a bit to send in the amended federal return so that the original is processed.  

You do not need to wait to send in the now correct state return after the changes are made.
