I'm not sure if I'm just overlooking it or its just not there, but you cant quit wars that've already started. SO I'm tryin to figure out what I need to do? I'm not really looking to wait an entire week to war again, and like I said I may just be over looking it

You should message someone from clan management about this. They should be able to help you.

I can't recall that being possible in the old version either - contact clan staff.
