Head is similar to a round, slotted head, except where the arrows point is like it was cut out. It is on an old double cylinder deadbolt. Wondering if I’m going to have to drill it out.

Hard to tell from the picture, but based on the description, that sounds like a one-way screw. See this page for some more information. Basically, the design is to make it easy to install with a regular screwdriver, but hard to remove, which is what you want on a lock. To remove it, you may need to use a screw extractor - basically you drill a hole into the screw, grab it with an extractor, and then unscrew the combined extractor + screw.
