How should I set the eggs when I quit turning them.

This is my first time incubating eggs. On Tuesday I am supposed to quit turning them. They have been in an automatic turner for the entire time. My question is, which way should I leave them to get them hatch most successfully? They have been standing on 1 end the entire time and I am worried that if I turn them on their sides I might cause them to drown or have some other problem. Should I cut out egg carton squares and stand them in those or should I just leave them on their side and they will be fine? Thank you for your help.
