where can i download a copy of TT 2023. My computer crashed and I lost the program. I bought it at Costco and the download link they sent me no longer works

Have you tried this Costco website - https://www.memberedelivery.com/

I bought the download from Costco for 2023.  Since you have to log in to a Turbo Tax Account,  the License Code and download are listed in my Turbo Tax account.  Access your downloads here
