No you are not within your rights. Follow the officer's advice. GO to court to evict. Self help will get you sued.

First, please understand that I am not licensed to practice in GA, so this is not legal advise but more commentary. I do not believe that law enforcement officers are in a position to know civil law either. Typically, an eviction is used when there is a landlord-tenant relationship. Your question does not indicate that there is rent owing, which to me implies that a formal rental agreement was not made.
If my interpretation of your question is accurate, then it is more likely that you would have to bring an action for "unlawful detainer", which is used when the guest comes onto the property by invitation, lawfully, but now refuses to leave.
If your daughter--and I have a daughter with whom I have to walk on eggshells we love each other but getting along is a different story--has left the home for just a few days, I would not consider that an abandonment. But again, this is not a landlord-tenant situation.
Coming to Avvo is a start, but you really need to consult with a GA attorney so that you are fully informed as to your rights and obligations. The police officers were well intentioned, but not attorneys.
