Need a little clarification on how to set this up properly. I pulled the old switch and there seems to be two neutral wires pig tailed together, a ground that’s screwed to the box itself, a hot wire around the top terminal and another hot wire backstabbed up top. There’s also the red wire backstabbed in the bottom. I purchased a pack of single pole switches and now I’m wondering if I needed a 3 way switch instead? Any clarification on what’s going on here would be greatly appreciated. Last picture is replacement switch.
