Mine did the same. Win10, desktop CD version, many hours of work and was saved to main drive every time. Started up to finish up and “obeyed” the turbotax update. Voila! There is no .tax2020 return to be found on the drive. No .tax2020 in my Recycle bin. All gone! Like Magic! I’ve been using turbotax for over 20 years now with no issues until now. WTH???
