Need 2021 TurboTax Download Home & Business

After being on hold for 94 minutes with Turbo Tax, the representative told me to go into my Account, click on "any year and licenses and download" which took me to the next page.  I put in the field the License Key, per her suggestion, but it does not bring me to a download option.  It says "unable to retrieve."  I suggested to her that perhaps it was because I bought it at Costco that year, and she said no.  It should come up.  

What do I do now?  Any suggestions?
