Yes, you can. When you start a new return in TurboTax Online, if you don’t choose a TurboTax Online file to carry-forward, then you’ll be asked “How did you do your taxes last year”. Choose TurboTax CD/Download and then select Continue. You’ll get a screen where you can choose a TurboTax CD/Download from your desktop.
FYI: this feature is only available in paid versions of TurboTax Online, so you will not see this option if you start a Free return.
