I use TD Ameritrade and I can assure you that the broker tracks disallowed loss from wash sales correctly.
IRS requires this, since 2012. Basis must be reportied to the IRS (Category A, D)
If E-Trade is not doing it, I don't know how they would get away with it.
You may want to switch brokers.
See also my replies above at 04-13-2022 1:44 PM, and earlier. It all still applies.
