My elderly parents live in my home I care for them and work full time but they are not dependent...Is there a tax deduction I can use, anyway?

No.

There's one possible exception. 

If your close relative cannot be your dependent because he had more than $4,150 of gross income, but otherwise would have qualified as your dependent (basically that you & other family members provided more than half his support), then you can include in your deductible medical expenses any qualifying medical expenses you paid on his/her behalf just as if he/she was your dependent.
