The car is running very rough. I need to know if the oxygen sensors are located in the front on top where they’re easy for me to get to because I am disabled.

Running rough can mean virtually anything, but normally it isn't O2 sensors. Usually, rough running is something like plugs or possibly a dirty throttle body. Do you have a check engine light on? What else has been tested or tried?
