I have been using desktop Windows Turbotax for years. Probably 25 years. It has always prompted me to save my file if I use the X in the upper right to close the program.
Only in the past couple of years has that stopped. So it is a hard habit to break. I have to make sure I use the file and save before I shut down the program. Even after I have done that, I will get a prompt to save my file when I close. But every once in a while, it will not give a prompt and if I forget to save before I close, then I lose my data! So I would say this is a new problem in the past couple of years and you now should save the file yourself BEFORE closing. I am having to learn the hard way to do this a different way than in many years past.
