I have the same issue with the state of Massachusetts. The positive flows through to the state, but the negative is floored at 0 so only the positive is shown overstating my income. As others have stated, this should flow through Sch 1, part 2 line 24z not be shown as a negative in line 8z.
Hope this is fixed by next year when nationwide 1099-ks will be sent to anyone with $600+ in transactions.
