Like I said above. I moved from NC to CO in December of 2018. I didn't notice until June of 2019 that my W-4 was not updated and I was still paying NC state income tax which is quite a bit higher than CO. My 2019 W-2 shows my income split between the two states but I never worked in NC for a minute. Is there a way to fix this? Do I file a state return for each state, or only file a CO return?
