Need Help ASAP

I clicked on a few things in iTunes and then it changed everything, so I went to restore with Time Machine and now its back the way it should be but I cannot tell if it duplicated everything or not.

My hard drive is 240GB and it is saying that only 93 or so GBs are available and I KNOW this is not the case, and its absolutely freaking me out right now.

Pictures: 24GB
iTunes: 10GB
Some videos: about 20Gb maybe


I have a screen shot which says I have a lot of backups taking up space, but everything is backed up to my external drive?

Please help me clear up some disk space, as I am not sure what the issue is right now.

I am also working on a project in FCP and it is probably taking up a lot of space, but I should be NOWHERE near the 100+ GB range.

PLEASE! HELP!

Thanks
