Installed TTax 2020 three days ago. Put in a few numbers just to get started (cant do very much like mortgage interest yet). Saved it (I thought) and came back to it today. I cant find my file anywhere on my hard drive. Before you put any serious work/numbers into it, make sure you are "Save As"-ing it to a real file name on a real drive cause an hour of my work three days ago was lost.
