Fidelity’s 1099-B only shows the Gain/Loss amounts before they have been adjusted by the wash sale amount.
Schwab’s 1099-B only shows the Gain/Loss amounts after they have been adjusted by the wash sale amount.
As far as I can tell, TurboTax downloads from both of them have appeared to show the adjusted amounts correctly, but the lack of industry standardization on the 1099-B forms makes it a little confusing.
