My PA state return, the income amount that Turbotax is displaying is not from box 16 State Wages, instead it is displaying the wages from box 1 of the W2. SHould I amend?

"the income amount that Turbotax is displaying" - to what PA form are you referring to and to what line?

In the PA interview, when you came to the screen for "Compensation Summary", did you edit the compensation from your W-2? If so, what was the initial amount that TurboTax showed here, and what did you edit it to?

Is the difference between box 1 and box 16 on your W-2, the same as one of the amounts in box 12 of your W-2, like for "D" (40(k) contributions)? If so, what is the amount and the letter code?
