You should speak with an attorney as soon as possible. It appears that the judgment creditor has filed a garnishment against you to collect against any wages or interest you may have in the business. The interrogatories are to the business, not you. If you begin answering on behalf of the business, you may actually cause problems for yourself in the future. Moreover, there are harsh consequences for the business if it fails to return the garnishment timely.
In short, contact an attorney.
