I'm having this same issue to where my Missouri, and Arizona state returns are being rejected. This is the message I'm receiving-
Description of error:
Your state return has been rejected due to a data mismatch on your form W-2.
What needs to be done:
There is a potential mismatch in form W-2, Box 18 (local wages) value on your state and/or local return. Double check Box 18 (local wages) of each of your form W-2 in the Wages & Salaries topic under Income or Federal. Change Box 18 to ensure it matches what is on your W-2 and follow the steps to file your state and/or local returns.
