This year I worked remotely and paid taxes on my income in two states (OH, NY). I just filed my taxes and realized I forgot to include the OH information from boxes 15/16/17 on my W-2. I need to amend my taxes now, but I'm not sure which returns I need to amend (I submitted a federal return along with IL/OH/NY state returns). According to the turbotax calculations, there is only a change in the Ohio return -- I should be receiving money back, no changes to any of the other 3.
When I start the amending process in turbotax, it's confusing because it seems to start immediately with the IL 1040X and asking if I have filed a federal 1040X, which of course I have not yet. I would appreciate to understand which of these forms I have to file at all and in what order.
