"This license code has already been associated with an account" with TurboTax Deluxe from Costco

I purchased a Costco copy of 2023 TurboTax Deluxe version. I tried to download the program to my MAC.  After I put in my license code. I got "This license code has already been associated with an account. Please check that account and look for it in Downloads." There is no TurboTax 2023 in my Download folder nor under Applications. Why does it not work?
