Thank you! In following up with my ex-employer, they confirmed that they gave me a W-2 that only reported income to IL. So the mailing address is my current NC but only IL was reported for wages that were Jan-Aug in IL and Sept-Nov in NC.
They refused to correct the W-2 and instructed to fudge my taxes. Since all my state taxes were reported to IL on the W-2, they told me not to list anything in NC. But according to your detailed instructions, if I can do the "just in case" steps, I can just allocate part-year returns. At lease me ex-employer gave me the calculations for my actual wages earned in each state.
Oy, what a headache!
