Toliet won't stop making a noise from the tank
Your tank water level is too high, you need to adjust it to be lower than the level of your overflow tube (the white tube in the middle of your pic.

You appear to have a fluidmaster toilet valve (the black thing on the left) there should be an adjustment knob sticking out on an arm that can be turned by hand or screwdriver. You need to turn it counter-clockwise a few turns. After turning, test by flushing. Adjust till the water stops at least a half inch below the top of the overflow tube.



Picture pointing out the adjustment screw.
