You will report your income on your federal, NY and NJ returns.
New Jersey does have state income tax. As a resident, you must report the income you earned in NY.
To insure you receive credit for the state taxes you paid to NY, you should complete your NY Non-Resident Income Tax return after your federal.
Complete your NY Resident Tax Return last.
