I did find 16 digit code and did enter it into TurboTax 2020, and still locked out. I shouldn't have to go mine for my codes after application are up and running!
Makes no sense that the same computer and application on it where I already filed return now locks me out. It forced an update prior to opening the application and then cut me off from using it. It gave me error code 605 with the 16 digit code.
