What do you do when you enter the licence code and it saids it invalid?

[Ismail Mohammad]

Activation says License code is invalid error code 603. 

[TurboTaxGinette]

Error 603 usually means that you are entering the code in the wrong version or that you have already activated the code. You possibly have purchased TurboTax Deluxe Online version and if so- you simply need to go here to activate your code turbotax.ca/activate.  If you have already done so then please simply log into your TurboTax online account. 

Thank you for choosing TurboTax.
