Changed redirectory link by accident!!

Hey guys, just a couple minutes ago I was messing around in my settings, and changed the root directory which links to absolutely everything, rather than re-rooting my home page to a different link on my blog, which is what my intentions were.

Basically the root directory is now https://trunkjunkquarterly.com/wp/?page_id=4% instead of https://trunkjunkquarterly.com/wp which is what it should be, and I can’t log back in to fix it all as all of the login forms are part of the directory which I messed up!

I am going to try copy my current root folder into a new one called ?page_id=4% and see if I can then login and edit it from there,
but just incase it doesnt work, anyone know where I can find the settings and change the root directory back to the original link?
