turbotax desktop 2025 premier - not importing 1099B from mutual fund companies - Vanguard, Fidelity, etc

I've googled and have found lots of users having same issue.

I go to import, am able to connect to financial institutions, get a message that it was successful, but then there is no information when I return to the program.

I have tried fixes recommend:

- turned off virus protection

- made sure cookies are not being blocked

- software, both windows and turbotax are up to date

- another solution states to download statements and then upload the pdf into turbotax - I do not see an option to upload a pdf into turbotax (I've seen it in prior years, but it never worked.  i don't see the option in the 2025 desktop version)

HELP!!
