I filed 3 2018 turbo tax files and when I open one it is going to another, the other one appears to have disappeared

it has the right extension and the name is different than the other one but the pointer appears to be going to the one currently there and the other file is gone.

if you used the same a/c to do all 3  returns the 2nd overwrote the first and the third overwrote the second so it would be the only return to exist. with online you need a separate a/c for each return but you can use the same e-mail for up to 5 accounts

if they over wrote each other how did they get filed?

Did you use the Online web version or the Desktop CD/Download program?  If you used the Online version then if you used the same account each return overwrote the prior one.  But if you have 3 separate .tax2018 files on your computer it sounds like you used the Desktop program.

What happens if you double click on a .tax2018 file?  Instead of  opening from the program?

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.
