My employer sent me a W2, then sent me a corrected W-2c form. I plan to E-file Federal and hard-copy mail State. When I imported my W2 info into Turbo Tax, it came in with the corrected info. Do I need to check the Corrected W2 box in Turbo tax? It seems like I would not for Federal, since I'm E-filing, but do I need to do it because of State?
