Ideally, you would not have used a journal entry to record the bill payment.  You would record the bill payment coming from a bank clearing account.  If you don't have one, set up a bank account in QB called 'clearing account'.  Then, after you have recorded the bill payment coming from the bank clearing account, create a journal entry - debit the bank clearing account and credit the loan payable.  This will put the bill payment into the loan and keep your vendor balance accurate.

If you already entered that bill payment into the loan payable, what journal entry did you use?
