Unfortunately, you can't transfer TurboTax Online returns into TurboTax CD/Download. TurboTax Online can't create .tt files, which is what TurboTax CD/Download uses.
TurboTax Online works on any computer that can use an up-to-date browser. So, if you start your Online return on a PC, you can finish it on your Mac (or vice-versa). You can also open the same tax return on our TurboTax App (for Android or iPhone).
