I am a part year resident of 2 states and received two W2 forms from 1 employer. 1 of them with nothing filled out but only the state wages and withholding on box 15, 16 and 17. Can I only mail this W2 form without any information about my federal wages and withholding with my state tax return? Or do I have to mail both W2 forms since the other W2 for the other state with all the boxes filled out.
