I ran into the same problem today 2/26/2023 and could not get TT to import my Charles Schwab Accounts. Saw the post about changing my password and exiting TT and then trying again. This did not work. I decided to use a different browser and this worked. My default Brave browser was able to authenticate my connection but the tax information never imported into the program. When I temporarily changed my default browser to FireFox then the complete process worked fine. Lesson learned: Try a different browser. Hey TT - please test Charles Schwab import with Brave browser - I'm pretty sure you have an issue there.
