Soft locked on the rescue Zee mission

I must have just skipped a large portion of the mission thinking I was going the right way. I never got the ability to force drag things from the ceiling or raise them. I never did the fight with Dagan. I ended up doing the waves of clones, beating them and then going through that cut scene and ending up at the bottom of the elevator or whatever you fall down. Now it is wanting me to use that force pull or whatever on the turrets at the top. Is there a way to go back through fast travel or load to a different check point?
