I will have to see if my brokers offer a 1099 unadjusted for wash sales for 2020. If I can get one I will probably take the approach you are taking. Report that net G/L amount on the PA schedule D and attach the “unadjusted for wash sale 1099” as support. Which brokerage do you use? I have some activity from Vanguard and some from Interactive Brokers.
When I ran into this problem in the past I simply made my gain on my PA state return the same as on my federal return. If PA accepted my initial return saying I had a $60-some thousand dollar loss surely they weren’t going to give me much of a hard time reporting an amended $6k gain and paying them more in taxes. Quite frankly at the time I was just so fed up with the whole thing.
