Thank you for taking the time to reply! Yes, they did not change the withholding in 2019 and used my 2018 allocations. I was still confused by the fact that I was paid for work actually done in NY in 2018, just next year. I believe that for tax purposes, only the paycheck date matters, and since I was never actually physically present in NY in 2019, I don't owe any tax to that state for this paycheck and W2.
I'm going over state return questionnaire for this company and getting the following results: I wasn't employed by the company in all of 2019, and there are no questions in the tax forms about years other than 2019. Considering this I assume that since I was employed by the company for a total of 0 days in 2019, I multiply my income by 0.
