ALL of your income including the self-employment income and your W-2 income must go on the same tax return---you do not file a separate return for income reported on a 1099NEC. It all goes on the same Form 1040.
You have self-employment income from DoorDash for which you will pay self-employment tax for Social Security and Medicare. You will need to use online Premium software or any version of the CD/download so that you can prepare a Schedule C for your business expenses.

You have another situation---you lived in two states. You do not say which state you moved from----but if it was a state with a state income tax you may have to file a part-year return for the state in which you had income from DoorDash and a part-year return for PA. Or were you in a state that has a reciprocal agreement with PA? What state did you move from?
