Amazon Seller – Finding account balance for a given date

Sorry if this information is already listed somewhere but I can’t seem to find it. My accountant is asking for a total balance on the seller account as of the end of the year. All the amazon business reports/statements seem to list an ‘unavailable’ balance. This makes me think there are additional available funds. I am looking for a total amount of funds from settled sales as of a certain date. I am not interested if a portion is unavailable for dispersement. Is unavailable the total? If not, does anyone know where I can get this number which represents all the cash in the amazon seller account (available and unavailable) so I can reconcile my seller account?
