Get your taxes done using TurboTax

After you bought it at Costco did you go to the customer service window to get the actual package with the License Code?   Sorry you got stuck in the Online version.   I buy from Costco too.  Don’t know what you can do now.  Take your receipt and cardboard back to Costco and try to get a refund especially since it seems you didn’t get the actual package.  Too bad you didn’t stop and post before you paid so we could direct you to how to install the Desktop program.
