I had the same issue. It appears that Turbo Tax asks for an 11 character password in order to import data; however, my password for Vanguard is only 10 characters and Turbo Tax wouldn't accept it. I had to enter each Account # and ID# for my 4 separate accounts - that info can be found at the top of your statement(s). I could copy and paste one of the sets of characters and had to type in the other one. I would change my password for Vanguard, but the last time I did that it screwed up my entries in Quicken. Ugh!!
My TRowe Price info downloaded with no problem with a 9 character password.
