I purchased Turbotax Deluxe 2023 at a warehouse club and installed the CD version on my Windows desktop computer running Windows 10. I successfully installed the software, checked for updates, and so on. When I went to "activate" the software, I was asked to enter the 16 character license code. I entered the code both with and without the dashes. No matter how I enter the code I receive the message "The license code you entered is not valid Error code 607". Note that I have used Turbotax many times in past years and never had this problem.
Can anyone help?
