State tax filing

Thank you for the quick response!  No, I am not claimable as a dependent.

 

Yes, I have to file as a resident of Washington DC by their rules.  Thank you for confirming that.

 

But seemingly, yes, I also have to file as a resident of New York State by their rules.  Before school, I lived in New York; I've accepted a job offer after school in New York; the reason that I am in Washington DC is for school; my drivers license, voter registration, permanent address for mail (such as for tax returns!), etc. are all in New York.  All that makes me a full-time resident of New York State too, yes?  That's my conundrum.

 

So, help!, what justification do I give if New York audits me?
