I'm not sure this answers your question, but since 11 months of your income was taxable by NY, it makes sense that most, if not all, of your total state tax bill would be due to NY. NY gets paid first.
All your income is taxable by PA, but since you can take a credit on your PA return for the taxes paid to NY - which has a much higher tax rate - it makes sense that your net PA tax bill would be zero or close to it.
