Part-Year Resident PA Tax question

Hello,

I lived in Pennsylvania until May 2024, where I earned income as a college student. I left PA in August for a full-time job in Maryland, where I earned income. My question is related to the special Pennsylvania W2 situations portion of my PA state taxes. As I earned income in MD after moving away from PA, do I need to check the box that says I earned income in another state (or does that only apply to income earned from another state while residing in Pennsylvania)? If so, how do I complete the Additional Information Summary? What form would this statement relate to? And what information would I need to include in the statement?

Thanks!
