No. Her income alone (>$4050) disqualifies her. You also probably do not meet the support test, since her loan money counts as support not provided by you.
There
are two types of dependents, "Qualifying Children"(QC) and standard ("Qualifying
Relative" in IRS parlance even though they don't have to actually be
related). There is no income limit for a QC but there is an age limit, a relationship test and a residence test. Only a QC
qualifies the taxpayer for the Earned Income Credit. At 24, she is too old to be a QC.
