Please make sure you purchased the Desktop/Download software and not the Online software as the license code is not interchangeable between the two. Could you confirm this please?

Thank you for choosing This.

I purchased the the Standard  package  which "includes CD & Download Option"

Please uninstall your Costco software, clear your cache/cookies, restart your computer and use our TurboTax link to download your 2023 Standard return. You can then try to use the original license code received with your purchase.

Thank you for choosing TurboTax.
