A journal entry was made by mistake back in January 2020.  It was a small journal entry and the date ended up getting posed as December 2020 instead of Dec 2019, it was reversed, however, the entry is still there as an entry beyond transaction date.  Now we cannot change our year-end date to this June or July.  The company is changing hands.  How do we get a data repair service to modify our data?

Thank you.
