Thanks for visiting us here, @KerriV.

I'll share some information about the A/P Aging report. You'll need to have a bill to apply for a credit or payment. This way, no vendor balance will be posted on the aging report.

To begin with, you'll want to pull up a vendor quick report to further investigate. Here's how:

1. Go to the Vendors menu, choose Vendor Center.
2. Right-click on the vendor of the bill in question, and select QuickReport.
3. Set the Date of the report to All.
4. Check if there are available credits (from unapplied bill payments, recorded credits, or journal entries to the Accounts Payable account.) This should be applied to a bill.
5. You can also select History (CRTRL+H) to see the details of the transaction.

If found, create a bill and then apply for the credit. Just go to Vendors, Pay Bills, and then click the Set Credits button. If you're unable to find a credit, it's possible that the bill transaction is damaged.

To resolve data damage, refer to this guide: Verify and Rebuild Data in QuickBooks Desktop.
