Hi, I got codes for bank 2 sensor 2 O2 sensor, but I'm not sure which side bank 2 is. I know sensor 2 is downstream -- after the catalytic converter but can't figure out the bank. Please help

Tried reading your owner's manual for info? If not there then perhaps a call or visit a GM service center and ask. All service manuals, manufacturer or aftermarket (Chilton or Haynes) will have this.

I got a code for my O2 sensor and it says bank 2 sensor 2. I know that it's a downstream sensor (after the catalytic convertor) but I'm not sure which side bank 2 is for my car.

The sensor is located on the downstream side of the converter towards the front of the car.

All "V" engines have one bank slightly offset to the rear of the other. The forward bank begins with cyl. #1 (then 3,5,7, etc.) the other begins with cyl. #2 (then 4, 6, 8, etc.). This rearward offset bank is typically regarded as "Bank 2." In a transverse mounted "V" engine the rearward offset is toward the driver's side.
