Can't find script source

I took over a site from someone else.
It’s a Genesis theme called Lifestyle.
The frustrating part is I don’t really know anything specific about the theme. However I added a jQuery AnythingSlider script in some basic way that has nothing to do with the specific theme itself.
The problem is, I can’t find where I put it. I’ve checked all files and pages. The only place it shows up is in the database. But, I know I didn’t edit the database to put it there.
Well, at least it works.
I just wish I knew how where that script text is located.
And, not just the script text, but the rest of the header info like the “DOCTYPE”, the “link rel=” text, meta tags, etc.
