No you cannot use the CD/download online. The license code cannot be used to pay for online software. Online and the CD/download are different platforms--you cannot move back and forth. When you use the CD/download your tax files are only stored on your own hard drive or any backup device you use like a flashdrive. They are not stored online and you cannot access it online.
Going back and forth between two PC's or laptops etc would be clumsy--you would have to save it to a device and move the files every time you change computers.
