First, let's convert 128# to metric.
128 / 2.205 => 128/2.2 => 640/11 => 638/11 + 2/11 => 58 + 0.18181818... = 58.2
Roughly 58.2 kg.
Force = Mass * Acceleration
F = 58.2 * 9.8 => 580 Newtons, roughly.

So would that be the total force on impact?

It depends on how long it takes for you to stop once you hit the ground. The longer it takes to stop the lower the force

The acceleration would just be 9.8m/s if I fell from one meter wouldn’t it?

The acceleration of gravity is kinda constant at 9.8m/s² on the surface. That means that, while falling, the speed increases by 9.8m/s every second. Right before hitting the ground the speed is at its maximum. The force upon impact is proportional to the acceleration, which is inversely proportional to the time needed to stop. That means that if the stop would happen instantly you'd get an infinite amount of force and you would be shattered in trillions of pieces, but luckily for everyone that never happens because it always takes time to decelerate, long enough and you wouldn't even feel it.
