Get your taxes done using TurboTax

If you understand about multiple brokerages, then you understand that a BUY with broker B can trigger wash sale with Broker A.

The loss with Broker A is disallowed and the BUY with broker B is adjusted.

You have to do these adjustments yourself, since your brokers don't exchange information about you.

 

This state of affairs is best avoided.
