Do your nonresident state first (NY) and your state of residence last (MA). Yes, it matters because this will do what Vanessa said: tax the income in NY and then bring that tax back to MA as a credit.
Just to be clear, you enter only one W-2, but enter multiple entries for boxes 15-17.
Yes, in a sense, you are being taxed twice on this income, but providing a credit is how states deal with double taxation.
