If you are going to claim the interest on a home equity loan as a business expense, then don't add it to Personal deductions or Home Office deductions; that would be 'double dipping'. Just add your original mortgage interest in Personal/Home Office. See Edited Answer for how to enter mortgage interest for Home Office.
