@jschwartz2425 --
Since you're a resident of NJ, ALL your income is taxable by NJ - regardless of whether or not your employer withheld NJ taxes. Your NY-sourced income is also taxable by NY - so you're entitled to claim a credit on your NJ return for the taxes you paid to NY. Note that the credit may not exceed the tax that you would have owed if the income had been taxed by NJ alone.
