Toilet still running

Replaced the flush valve it seems as though it doesn’t fall down and seal properly then it also seems as though the water is going over top op the valve and running?

In the 2nd photo, you adjust the fill level with a screwdriver.

The screw doesn’t seem to want to turn

They are designed to adjust both ways, and yours appears to be at a "stop", however adjusting the other way will raise the float, and the water level, which would be counterproductive, so the other adjustment is in the telescoping fill valve, and in this case should push down, which intern will allow the float to be adjusted with the screw.
