The Turbotax update did not erase my data. When I began my new return I browsed to a separate hard drive where I had last year's return data and imported it from there. Apparently from then on, when Turbotax saved my inputs for this year, they saved them to that hard drive file. I didn't realize that hard drive (it's an external one) was powered down. That's why when I restarted Turbotax yesterday after an update, it couldn't find the files.
