Intuit won't sell  2021 to you. Just don't buy from Mercari. I just bought QB Desktop for Mac 2020 and it its unusable. They sent me a piece of paper with a google drive link in it that is so many characters it's impossible to type. It took me more than 72 hours to request help and I'm told by Mercari my time to provide feedback to them has expired. I think it's been less than a week. Perhaps Mercari believes everyone works on its schedule. I don't recall seeing anything about the feedback window expiring. Plus,Mercari sent me a link to communicate with the seller. The link didn't work. Haven't been able to find an installer on Intuit's website, as the seller advised. Last I spoke with Intuit, they advised 2021 was available somewhere but to be aware of scammers. Guess I just got scammed.
