most likely you power steering reservoir (towards the front of the left wheel well). The oil dipstick is in the middle of the engine bay and has a red handle.
The ATF dipstick (if you have one, and you should since you have the same year and model car) is near the oil dipstick but closer to the windshield. It is a black handled little item that looks like a 1.5" can. Push towards the rear of the engine and lift up. When you are first trying it, it can seem to be stuck but keep at it. I find that the best method to get it started coming out is to slightly tilt the handle and lift.
Check the ATF while the engine is at operating temp and running.
