It is turbo tax. I having been using Turbo Tax since 2011 and never had an issue, until this year.. I use a 2018 Mac desktop. The soft ware would not open either in the download version or the disc version. I called Apple. Apple was great, it has to do with emptying cache. It now works and Apple saved the day. If you use Apple call their support line. I requested a call back and they called back when they said they were going to.
