Thanks for all responses. I am a woman learning as I go. I will take a look underneath and see if can see exactly where water is coming from.

If you are filling from the gravity fill port:
It might be coming out of a hose from a low point drain off your holding tank. As you gravity fill your water tank the open petcock will allow the water to simply drain out the open tube at the bottom of your tank.
If so that petcock needs to be closed.

Many people leave them open to insure complete drainage of the tank and never close them during the winter months. The holding tank and drain line stays dry all winter once its drained out, so there is nothing to freeze and no anti-freeze goes in there .
