I assume you live and work in NC ... if this is not true then the advise below is not right
When you completed the 2017 tax return and keyed in the w-2 did you type in NC or KY for state withholding? If you typed in NC that is why TT did not flag anything; how would it know?
You would have to submit a 2017 tax to WV return showing no income and the withholding so that you get that money back
Then submit a amended 2017 NC form because you will owe NC The money that WV now has
