Get your taxes done using TurboTax

Probably blind luck the way the day is going, but . . . 

1. made sure the 3rd Party switch was thrown on the Schwab account.

2. Using Safari (I'm on a Mac), I cleared the cache and cookies.

3 Then rebooted.

4. Then logged in to Schwab and, Voila-- it let me in .

Good Luck.
