The bill shows as "PAID", but shows up in the "Pay Bills" with no credits to post against it. I followed the steps as you laid them out, but now I have a balance owing that shows up in my A/P aging report.
I'm here to ensure you can remove the balance that shows in the A/P Aging report. This way, you'll be able to record your payments and keep your accounts accurate.
Since you already paid the bill, you can unlink then link the payment through the A/P Aging report. This will let you refresh the payment's connection so the bill will no longer show in the report.
Go to the Reports menu.
Select Vendors & Payables.
Choose A/P Aging Detail.
Locate the bill, then double-click it.
Unlink the payment, then click Save & Close.
Then, locate the bill again to link the payment.
Click Save & Close.
I've attached screenshots below that shows the first to the fifth steps.
In addition, you can customize the A/P Aging report to filter the specific information that you want to appear in it. This allows you to select the available columns, add or remove information on the header/footer, and even personalize your fonts. For the detailed steps, kindly visit this article: Customize reports in QuickBooks Desktop. It also contains other related articles about reports in the desktop version of QuickBooks.
Please let me know if you have other concerns. I'm just around to help.
