Trying to balance out my accounts.  Some transactions go back 8-10 years.  Some are credits and debits.

Need to know the right procedure to correct these accounts.

Thanks for the prompt response, denise36. Let me provide details to help you with ensuring your accounts get balanced in QuickBooks Online (QBO).

To get your account balance and books accurate, I suggest reconciling your accounts by referring to your bank statements.

Performing the reconciliation process will help you know if you need to delete some of your transactions, either duplicate transactions or transactions that aren't showing up in your bank statement. Moreover, you can also generate journal entries to adjust the balance of your accounts. You may also seek assistance from your accountant to ensure that your books and data are accurate. 

Additionally, you can visit this article to view the guidelines that will guide you in reconciling the transactions: Learn the reconcile workflow in QuickBooks.

We're always here in the Community to help if you have other questions about managing your accounts in QBO. Keep safe, and have a great day ahead!
