TurboTax Business is a desktop download software that can only be used on Windows. The only way to use that version is to purchase the download and use the license code to download it.
If you used online TurboTax Business it could only have been a "Live" Assisted version or a "Live" Full Service version. There is no "do-it-yourself" online version of TurboTax Business.
So--you need to determine what version of the software you used.
