@lonelyboy22 --
When you're on active duty your state tax obligation is to your military SLR (State of Legal Residence). If your military SLR in 2019 was NY, then for tax purposes that year you were a NY resident - even if you hadn't lived in NY for a number of years.
Your military SLR doesn't change unless you formally change it with DFAS.
This reference explains how NY taxes military pay:
