I have been seeing the exact same error messages and after many hours, like you all here I can finally get to the Schwab login screen. Now, for the last hour, it keeps telling me that "Login is temporarily unavailable. Please try again later or call customer support". Am I supposed to call Schwab customer support or TurboTax? I have no problems logging in to Schwab, both on Desktop and Mobile. I have TurboTax Premier Desktop on Mac.
