I entered a vendor bill and it's showing up on our balance sheet as Interest Payable. I'm not a QB expert so I just assumed it would show up on under A/P. How do I fix?

edit the bill, you must have used that account as the expense for the bill, change it to what expense it is

If you have a loan, and you are entering interest assessed, and your loan is an interest only loan, then this entry would use interest expense on the bill.
