Unfortunately, you can't transfer last year TurboTax Online information in TurboTax CD/Download. TurboTax Online can't create .tt files, which is what TurboTax CD/Download uses.
You can still print or download a PDF copy of your TurboTax Online return. Please see this TurboTax FAQ for instructions: How do I print/save a copy of my tax return in TurboTax Online.
Thank you for choosing TurboTax.
