Hmmm...if she live there all year round, probably OK to use that College address.
BUT
IF she moves around, or leaves for the summer, it might be best to use your home address....just in case there is any correspondence from the IRS that must be replied to...you/she doesn't want it being sent to an address where she is no longer there...or at least has someone there reliable to help (i.e. yourself). Mail forwarding doesn't always work seamlessly, and some Govt letters have "Do Not Forward" on them.
