I have some information that I want to share so you'll know why this is happening, Kerissa.
Generally, the Accounts Payable Aging report is not going to match with the Trial balance. Like any other Accounts Payable Detail report, the Aging report doesn't include bills with a status of Paid.
The Trial Balance pulls up from the General Ledger that will take into account all transactions to that specific account including manual Journal entries and posting from other accounts. Whereas the A/P Ageing or the Aged Accounts Payable report will pull only those invoices that are outstanding and are recorded in the A/P account.
You'll want to run other vendors' reports so you'll be able to get the data you need. Just make sure to customize them so it shows up the information on the different areas needed for your business. Here are the reports that are exclusively included with your subscription. Go through this article for more details: Reports Included In Your QuickBooks Online Subscription.
Please keep in touch if you have any questions when running reports. I'm always one post away if you need further assistance.
