Why can't I find the basic version of turboTax to purchase and download from older years?

I need to purchase the downloadable turboTax software for 2021, 2022, and 2023.  When I pull them up, the lowest version available is "Deluxe".  Deluxe is $30 more than basic, and I don't need state tax or special help.  Am I only able to purchase Deluxe for these years?
