Unsuccessful imports from both Schwab and Fidelity

I'm running TurboTax Premier 2024 (freshly updated to 024.000.0308 on a Windows 11 machine.

I've attempted to import financial forms from Schwab and Fidelity.  In both cases I get the following error.

I'm reasonably certain that the data is available because I have downloaded pdf versions of the forms.

I'm at a loss about what to try.

Thanks in advance!
