I answered with a footprint because your question is in the category “footprint” and you specifically ask for a footprint in the first post. I am a bit confused why you now talk about symbols.
It might be a good idea for you to read up on what symbols and footprints represent
There should be a Oscillator symbol lib as well but it might not be added to your project.
Use the eeschema->preferences->component library dialog to add libs.
More details about that see: Where are the momentary bush-button switches located?
