You will first need to complete your federal income tax return.
When asked if you made income in a state where you don't live say yes.
Then complete a DE non-resident return but only showing the income you earned while working in DE ( I assume you had no other DE sourced income). Since no DE taxes were withheld, you may owe a balance due to DE.
Nex complete a PA resident income tax return showing ALL income, even that earned in DE. Be sure this return contains a PA Schedule G where you show the income that was earned in another state (wages) and the tax liability paid to the other state. Schedule G should compute a credit on the PA tax return so that the DE income is not double taxed. The PA taxes withheld should show up on this PA return.
TurboTax won't prepare your PA local earned income tax return but all your earned income (W2 and self-employment ) is reportable on the local earned income tax return
