Reply to comment by silverbullet52 in Neutral line - Kasa smart switch install by Inarus06

So that I understand correctly - I have three wires coming from one line. White, black, and copper out of three sets; white, black, and red out of a 4th. 4 lines in.

The black is load, white neutral, bare copper is ground.

The red out of the 4th line (no copper on that wire) is my switched hot, aka a runner?

Black is usually hot. Whether it's line or load I can't tell from a picture after things have been removed. Red would typically be going from a switch to an outlet or light. Or whoever did the original wiring ran out of black and used red. It happens.
