System blowing hot air while on AC mode

I just installed my Nest and might have messed up the wiring. After setting it up, the system is blowing hot air instead of cold.

Old system had these wires: Y2, W2, G, W, C, Y, R, and a jump wire from R to Rc.

Old system wires to new system wires: Y to Y1, Y2 to Y2, G to G, W to W1, W2 to W2/Aux, R to Rh. I'm wondering if R is supposed to go to Rc?

Edit: I followed the troubleshooting instructions in the Home app (Home --> Thermostat --> Settings --> Thermostat --> "Scroll down to heat pump" but heat pump is not showing up as an option

If you still have it, post a picture of the original thermostat's wiring.
