The oval handle on the wall or floor behind the toilet. Turn it clockwise.
If the valve will not turn, take the tank lid off and lift the float to stop the tank filling.
Toilet water can be contaminated. Wear gloves, disinfect the floor, and keep children and pets away.
Water around the base can mean a failed wax seal. It soaks into the subfloor and ceiling below where you cannot see it. Do not keep using a toilet that leaks at the base.
A clog in the toilet or the line beyond it.
Failed wax ring or loose flange.
Flapper or fill valve wear. Wastes a lot of water.
Needs replacement. Close the valve and do not use it.

Usually the wax ring seal has failed. Stop using the toilet until it is reset with a new seal.
Not usually, but it wastes water and raises bills. Close the valve between uses until it is fixed.
