I sold land in 2018 in Hawaii and paid HI taxes at the time of sale, I live in Pennsylvania. Do I owe state income taxes to both states?

You file a non-resident HI return and then a resident PA return.  Both will report the HI sale of land.

Only the PA return will have a credit for the taxes that were paid to HI that are on the HI return.

This prevents both states from taxing it by having the credit.
