If you are standing on the ground, the only actual force is the normal force of the ground acting on your feet to stop you from falling into the center of the Earth. However, it feels like you are pushing down on the Earth, but that's technically a pseudo-force.
Another way of looking at it is to imagine that you are standing in an elevator in space that is accelerating with the speed of 1g. That scenario will feel exactly the same as if that elevator was standing still on the surface of the Earth, but it's more clear that the elevator is pushing you, and not the other way around.
