I am a NYS full time resident who I was working on my taxes this week with Turbotax online, I found out that one of my employers, that has its official business address in NJ, withheld NJ state income tax, but not NY state income tax, from my paycheck. I don't think this was correct, because I did not actually physically work in NJ for this employer, but in NY.
However, now I am stuck with a big tax bill AND underpayment penalty to NY state, and it seems I must file a nonresident tax return for NJ state just to get back the state income tax that was withheld. It also seems from other answers to similar questions I read here, that I have to complete the NJ tax return BEFORE I complete the NY tax return, but unfortunately I have already completed (and paid for) my NY return, I only realized the mistake in my final review of my returns. So, is there anyway to fix this? Is there a way to delete my NY tax return, complete the NJ tax return, and then complete my NY tax return again?
