You cannot claim your daughter's medical expnses, since she is not your dependent. You do not qualify for the "medical dependent" exception.
"Medical Dependent". If your close relative cannot be your dependent only because she had more than $4,300 of gross income, but otherwise would have qualified as your dependent (basically that you provided more than half her support), then you can include in your deductible medical expenses any qualifying medical expenses you paid on her behalf just as if she was your dependent.
Note: the medical dependent rule would only apply, in the case of a potential qualifying relataive, not a potential qualifying child dependent.
