Anthony was sentenced to a year of probation after pleading guilty to stealing checks from a friend.
Her attorneys say the time was served while she waited for her murder trial.
The AG's office has filed papers opposing her attorney's efforts to stop the probation.
Anthony was acquitted last month of murdering her 2-year-old daughter, Caylee. She has kept a low profile since her release from jail, and her exact whereabouts have been a secret.
