Same thing happened to me today when I tried to buy the download version of Turbo Tax 2019 using the latest edge browser, but now they do not seem to support internet explorer (IE) anymore, it fails in IE when I try to use that to do the download like I did last year. But thanks to the reply below, I tried to open a "new inprivate window" in edge and purchasing from the inprivate window works for some reason.
