I can confirm that changing the password so that it only contains alphanumeric and @ works. The import from Wells Fargo Advisors worked and it did not ask for 2-factor authentication. I first tried calling Wells Fargo customer service and they were spectacularly unhelpful, saying that they do not support TurboTax issues. Whew! I thought I was going to have to enter all that data into TurboTax myself.
