Hi, in 2018 I relocated from NY to NJ. 2 days prior relocation I sold stocks. While filling the tax return for 2018 I "assigned" the stocks capital gain to NJ, and paid taxes to NJ. Looks it was a mistake, as two days back I received the "statement of proposed audit changes" from NY, which mentions that I must pay the stocks capital gain to NY State and NY City. It is about 4k.
I realize my mistake - I sold stocks Before relocation, so I supposed to pay taxes to NY,NYC and not to NJ. And I will, but how to return taxes I paid to NJ?
