Before I go up there… all I have to do is shut off the same breaker as before? No other breaker I don’t know about? I assume that’s not a stupid question even though that breaker shut down the air earlier

The common wire wasn't used by the old thermostat. It's probably not connected to the control board on the other end, thus no power. Have you checked it with a multimeter?
This would be my guess - when I upgraded to a smart thermostat - I needed to connect the blue (common) wire to the control/circuit board in the furnace. It would not be connected if the blue common wire wasn’t used/connected with your old thermostat.

Found the blue wire!
Is this where I’m plugging in? Only available spot is on the left

There should be a diagram that labels the c terminal on the panel.

Nm, I see it marked at the end where the white wire is.

So plug it in with the white?

I was today years old when I learned “common” was just another term for “neutral”. So I’m guessing it’s ok to add that blue wire to the C Terminal with the white
