If you used the Desktop program......
Do any of the returns have the same name initial as you or your spouse? There is a problem saving returns if 2 returns use the same initials, one will overwrite the other. So you have to be sure to save the returns with names completely different to keep them apart. Don't use the default name given by the program. Go up to File-Save As and give it a unique name.
Yes they could all be filed if you filed one before starting the next return.
