When going to the "Amend (change) 2021 return dropdown from the home page, the only instructions are to download a .tax file and desktop turbotax to amend with the application. This application, when I tried to download it, is not compatible with windows, only mac. There are no other options in the dropdown to amend online. So how do I amend my 2021 return? I can't speak with a representative since the help bot says I haven't started a return or chosen a product.
