Just came into possession of an avocado tree. It is a single trunk of about 4 feet. Shouldn’t it have been pruned so it would branch? Is it too late to do so now?

Yes, I think you're right. You can prune it back now- you can remove up to 1/3 of the height of the tree's main trunk.
Another factor is that low light levels can cause a plant to grow excessively tall with no branching. Avocados are sun-loving plants with similar growing condition preferences to citrus, so the more light they get, the happier they will be.
