@Mothic4 :
If you live in NY and work in PA, your work income is taxable by both states.
If the postal service will only withhold taxes for your work location in PA, you may want to start making quarterly estimated tax payments to NY. That's because NY's income tax rate is considerably higher than PA's. So, although you'll be able to take a credit on your NY return for the taxes paid to PA on the income taxed by both states, the credit will only cover a portion of your NY tax obligation - leaving you with a balance due to NY.
You can find information about NY estimated taxes here: https://www.tax.ny.gov/pit/estimated_tax/default.htm
