Can not import 1099 from Vanguard

Can not import 1099-r or 1099-div from Vanguard.  I enter account number and document id and it says the import is complete, but it is not.  I was never asked for my Vanguard username/password.  What I am missing?

Turbotax Premier on Windows 11 desktop.  Long time turbotax user and have imported many form in the past.  What is different this year?
