Hello I don't understand what the jumper is for. How I'm supposed to select that I want 3.3V TTL and also draw power from the module?

Hi Riataman , thanks for reaching us. the jumper is to link TX and RX, in order to test and validate data reception.

seriously? I am not sure who you are but the jumper connects either 5 or 3.3 V with vcc, ithas nothing to do with validating data.
