I always file desktop. I py for Deluxe which included five returns. I file one or my wife and another for our Niece. TWICE now in three years the second file has overwritten the first file! I believe overwrite is the default. WHY. It is far too easy to overwrite the file than it is impossible to recover it. First off I want ti so I will not need to start from scratch next year. This year, I need to file an amended return. When I pull up my own return it is gone - Replaced apparently by My niece's return. After the first time I asked that the default is NOT to overwrite. To Overwrite should only be after a BIG RED pop-up warning that you are about to overwrite another return. had I known that this fault still existed I would have saved my return on a Thumb drive. Please don't let others have to learn the hard way.
