That error indicates your sign on information is incorrect. You would need to contact Charles Schwab for assistance. They may require two factor authentication to sign on to a third party.
When I try to download data from Charles Schab, Turbotax asks me to verify my Schwab password. I click Continue and nothing happens. How do I verify the password?
I signed on to my Schwab account with the same password that I posted for Turbotax and my accounts opened up as usual.
