There is a difference between a license code (for Desktop) and an Activation Code (for Online). These codes are interchangeable.
If you have bought TurboTax Online, please go to turbotax.ca/activate to use your code before you start your returns. You can see this TurboTax FAQ for step-by-step instructions: In TurboTax Online, how do I use a prepayment code?
Please keep in mind that the code can only be used once per account. Using the code again will result in an error message. It can only be linked to one account. Additionally, TurboTax Online and TurboTax Desktop codes are not interchangeable.
