ALL your income is taxable by your home state of PA.
Unless you are working remotely as a requirement of your NY employer, and you are assigned to or working from a bona fide PA office of your employer, your remote work income is also taxable by NY.

In that situation you must file a non-resident NY return in addition to your normal home state PA return. (You should also file a non-resident NY return if NY taxes were withheld from your pay, so as to receive a refund of any excess NY withholding.)
You'll be able to take at least a partial credit on your PA return for the tax you pay to NY on the income taxable by both states, so you won't be double-taxed.
In TurboTax, be sure to complete your non-resident NY return first, before you do your PA return, so that the credit is calculated and applied correctly.
