2008 sentra started smoking heavily after being parked while running with A/C on

Had the car running on and off for about 2 to 3 hours. When I put the car into drive huge clouds of white smoke started coming out and it was hesitant to accelerate. Last week it also got really warm under the cup holder area

Car has a transmission code, cat code, and started consuming oil last year. It was tested for compression last year and came out fine. Coolant level in the container is above minimum but does have a small drip leak in a hose. Just wondering if the white smoke could be due to overheating from running it with the AC in 80 degree weather.
