Wiring to e nest

[Sahuarokid]

I am install a e nest thermostats stat. The following wires were connected to the old thermostat:

Y1, G, O (white),

there was also a jumper wire connected to the Rc & Rh connection. I know I don’t need to do anything with the jumper but I did find another blue wire coming out of the wall that wasn’t connected to anything on the old thermostat. My question is whether I should this blue wire to anything on the nest thermostat

thanks
