Thank you for that information.  But how would I know it changed when I open the file unless I had a photographic memory.  Also, isn't there a "warning" that comes up as a worksheet alerting you that you are changing what was initially filed?  There was no alert or warning or error message to let the preparer know Pro-Series decided to work in my office, go into my computer, and change returns I filed.  I guess that "employee" deserves to be fired.
