The TurboTax desktop CD/Download editions and the TurboTax online web-based editions are separate programs. You can use one or the other, but not both unless you want to pay for each edition and not use one of the editions you paid for.
Go to this TurboTax website for the online editions and either sign onto your existing account or Sign Up for a new online account - https://turbotax.intuit.com/
