First, please make sure that you have purchased the right product. The codes for TurboTax Online will not work with TurboTax CD/Download & vice-versa.
Second, if you bought TurboTax at a retailer (Costco, Walmart, Staples, etc…), please make sure that you are using the code that came in the package. It may be on a slip of paper or on a scratch-off card. It is not on the outside of the box or on your receipt.
If you have bought TurboTax CD/Download, you will be asked for the licence code when you install the software. Please see this TurboTax FAQ for more information on the licence code: Where is my TurboTax licence code? You can download the current version of TurboTax CD/download edition here: Choose the 2023 TurboTax edition you need (for Windows). You can download older versions of TurboTax CD/download edition here: Where can I download the CD/download edition of TurboTax?
If you are still not able to resolve your code issue, please contact our phone support team at 1-888-829-8608.
