20A in the garage? Code allows a non GFCI 20A in a garage for a freezer/fridge.
15A might be motion lights on front/rear of house or the garage door circuit.
15A might also be hard wired smoke/co detectors or doorbell transformer.
Also might be an attic light or attic fan(power vent).

No garage. No powered vents in the attic. Yes, as far as I know there is only one kitchen outlet circuit. The house was built in 1978. The unknown 20A isn't any of the kitchen outlets, nor is it the fridge circuit. It isn't the well pump, that is 240V. No pool pumps or anything like that. It isn't the condensate pump. I think I am going to have to try and trace the wire to see where it goes. It might be something like the range hood. I turned it off a bit ago and walked around testing all the outlets I could find. It isn't anything obvious. This also isn't super-critical. It's just been a nit for me to pick for a while. I hoped there was an easy way to do it that I was missing.

The simpliest solution is to turn off all three circuits and go about your business. In the next couple of weeks you'll find whats not working then go flip them on one at a time to check which circuit it is. All this other nonsense has you doing too much work!

When we bought this house, the panel in the basement was missing some labels and the ones that were there some were wrong. After I upgraded the panel I'd planned on identifying all the circuits but kinda ran out of time. I have 3 that I still don't know what they are for. I have a borrowed circuit identifier - you plug into a wall socket then it beeps at the panel but I don't know where to plug it in. I tried shutting off a breaker and seeing what doesn't work, but not finding anything that doesn't work. Short of pulling the front of the panel off and trying to trace cable, is there anything else I can do?
The easy way is to find a helper and start over. Start in any room and identify each outlet - one person looking at the light plugged into a receptical and the other throwing breakers.
It is best to turn on all the wall switches. 3-way switches are tricky. Equipment with on/off cycles are difficult.
Go through the entire house and the exterior.

Turn off the breakers you can't ID and forget about it until you find something that isn't working 
Make sure fridge and freezers are still on.
