Misc. Deduction

I'm a little confused by the misc. deduction section - I am maxed out on Interest deduction as well as Taxes... however, my biggest deduction is falling in this Misc. Deduction section - do you know what that is?  I dont have any other deductions filled in like disaster relief.  The explanation says other miscellaneous deductions come from your miscellaneous deductions that aren't subject to the 2% adjusted gross income threshold. -- But I'm not sure what that means?
