Unfortunately that is not the issue.   The software is just erasing the return.  No one else is in the return, I have it set to automatically save, I resave before I close the return, I print a copy as a pdf so I can re-enter all the information quickly when the software deletes the return.   I am also on the network, same as everyone else.    We may just need to switch to another software that does not experience this same problem.
