What I found for Turbotax 2022 Desktop on Mac was that
1. restart computer
2. start turbotax
3. Retry import of Schwab data
4. When the request for the Inuit Id showed up, gave no password, selected "Always Allow"
5. Got an Inuit web site log in pop up.
6. Used my Intuit web site credentials there.
7. Now the desktop app is authenticated with Intuit and can access Schwab.
Mysteriously could not log in via any menu selection.
