PA part time resident (moved from NY): How to properly allocate between states on PA return?

Hey all, this question is specifically for the compensation summary section on the PA state return. As background, I'm a remote worker for a company based in NY, and I moved from NY to PA at the end of the year.

My W2 splits my income between NY and PA, so this section shows two rows for my employer, one with a PA state code and an NY state code. For each row, I need to say whether the income is taxable by PA, and what amount of it is taxable.

The NY state code row shows all of my income for the year. The PA row shows the income post-move. As another wrinkle, my location information was adjusted slightly late, so the PA row is undercounting the amount I earned in PA (shows ~5% when it should be ~15%).

My questions are:

1. Do I say any of my NY state code row is taxable in PA, and if so, how much?
2. Should I update my PA state code row to reflect the undercounting (i.e. raise the 5% to 15%)
