Get your taxes done using TurboTax

Just tried to download transactions from TD Ameritrade to 2020 Desktop version of TurboTax. I installed from CD that I [purchased in store and have updated accordingly). Was able to import my W2's OK. When I went tp import my stock transactions from my TD Ameritrade 2020 1099 forms I got the following error message  today. 

 

TurboTax  Home and Business 200

TD Ameritrade

Invalid sign on

 

Please advise on how to fix.
