I spoke with Schwab, who confirmed that there was a glitch in the interface between TT and
Schwab. Apparently, each financial institution has unique procedures that they work out with Intuit for the imports. Schwab and Intuit appear to have fixed the glitch as of morning 3/13/22. Now when you proceed with an import from Schwab, you should get a pop up window asking you to sign into your Intuit account. From there, you'll agree to their terms and input your Schwab credentials.
The imports mostly worked from there. Oddly, there was still a glitch at Schwab with linked accounts. I never could get it to import the 1099Div and 1099INT for my wife's accounts even though it listed those forms for import. Instead, it kept duplicating those same forms from my account. Weird. Worked fine for her 1099R, but could not get her other 1099s after multiple attempts from different angles. I had to hand enter those two 1099s.
