So I am also attempting to file my amended 2021 returns. In TT2021, it states "You can efile your amended returns." I go through all the screens and then it pops up about the dates not being available. If it is a requirement to file by mail, WHY DOES TTAX STATE THE AMENDED RETURNS CAN BE EFILED? I was relying on the ability to efile them, only to find this out just now. THIS IS ABSOLUTELY LAME AND VERY ANNOYING.
