In a statement, corrections officials said that Anthony reported for probation sometime Wednesday evening. No other details were immediately released by the department.
The announcement comes a day after an appeal court delivered an order stating that Anthony did not serve her one year of probation in jail while awaiting trial in her daughter's death.
Anthony, recently acquitted of major charges in the death of her daughter, 2-year-old Caylee Marie, was ordered to report to corrections officials by noon Friday.
Though officials confirmed that Anthony reported for probation Wednesday evening, no details of the circumstances of that report or the status of her probation were released.
However, her lead attorney told Fox News that she plans to serve her probation somewhere in Florida, and will not be required to be employed. She will take classes online, attorney Jose Baez said.
"She told the officer she understands the conditions of her probation and she was told the date for her next appearance," Baez told the 24-hour news network.
Department of Corrections officials plan to make a statement regarding Anthony's probation status at 11 a.m. Thursday at the department's office in Tallahassee.
Questions about Anthony's probation arose after her acquittal. It wasn't immediately clear whether Anthony should serve probation for her check-fraud convictions upon her release from jail.
DOC officials initially stated Anthony had served the one-year probation in the Orange County Jail. That, however, was not the intent of the judge who imposed the sentence, Stan Strickland.
Anthony's defense team argued she'd served probation while in jail and could not be made to serve again. However, Orange-Osceola Chief Judge Belvin Perry and the appeal court were not convinced.
