I do not recall having to have or use a holster at a CHL class or renewal.

There are several CHL instructors on the Forum who will probably answer more fully, but my experience is that you have nothing to worry about if you do not have a holster yet.

You can unload your pistol, check it to be sure it is clear, and practice your draw at home. (Aside: they call it "presentation" - a colleague once asked my why I cracked up when she said she was going to her office to "practice her presentation" - she meant the PowerPoint kind).
