@kathleenv2 --
For state income tax purposes, your daughter has a situation of dual residency.
She is a statutory resident of New York because she will be in New York for 184 or more days of the tax year, and she will maintain a permanent place of abode in New York for substantially all of the taxable year.

She is a domiciliary resident of Pennsylvania, because she intends to return to her permanent home there after her year's temporary absence. Therefore she has not changed her domicile.
She must file a resident tax return in both NY and PA. He domiciliary state of PA will grant her an "other state credit" for the taxes paid to NY. The credit may not exceed her taxes due to PA. In TurboTax, she should file her returns in this order: federal > NY > PA.
