Ender - 3 Levelling issues

I just got an Ender 3 and have put it all together and the next step is to level the bed. I selected auto home and then turned off the motors so I can just the bed with the screw, but I’ve put the bed all the way up with the screws and it’s still not getting close to the nozzle. Not sure what else to do and can’t find any videos or anything. Hope you can help thanks.

A normal Ender 3? Not any of the newer Ender 3 Neo, S1 or V3 series?
Is the position of the end switch correct? It can either be the print bed or the end switch on these machines without ABL.
