Away at school I made all my income in NY. My permanent residence is NJ. I'm amending my return so why am I getting refund from NJ if I did not work in NJ?

Also, I have to amend my return  to correct my dependency status question. My mom said she has my name on her return because I still live at home and was attending school full time however, she cannot claim me of course because of my age (26) and my income for 2019 (9,336). I just realized I mistakenly clicked someone can claim me but my returns were accepted. Will the IRS correct that readjust the calculations  and send me a notice?
