Multiple state filings [IL, OH, KY]

[HB95]

I am an undergraduate student at a university in Ohio with my primary residency in Illinois and my employer based in Lousville, Kentucky.

My company is based in Kentucky and the W-2 that I received was 3 pages [p.1 had 100% wages for federal and my IL wages for state; p.2 had $0 federal wages and my OH wages for state; p.3 had $0 federal wages, $0 state wages and nominal amount in local taxes for Louisville).

I think of this W-2 as one form, with 3 pages because it does not allow for multiple state entries on it. The 3rd page is needed because it is for local taxes paid in a 3rd state.

My questions are: 

Q1 - how do I know if I need to file multiple states? I would think I needed Ohio, but when I paid for and downloaded Ohio, only then does it tell me that based on my entries, I do not need to file Ohio state tax form.

Q2 - if that is true, then can I get refund on my download earlier this afternoon?

You need to file Illinois as a resident.  You will need to file a nonresident return for the states you worked in- so if you worked in Ohio you would file an Ohio tax return.  If your worked in Kentucky, you would file for Kentucky.  Note: if your employer withheld Ohio taxes (on W2) but you worked in Kentucky, you would file an Ohio return to get the withholding returned.
