I can help you fix your incorrect beginning balance, @dyw1997.
This could be caused by the changes made to the reconciled transactions when you moved from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO). I can guide you on how to resolve this.
1. Before checking your opening balance, ensure that your opening balance is correct.
2. Check your bank statement and make sure that you're reconciling the correct account for the correct month:
- Navigate to Transactions, then choose Reconcile.
- Pick an account that you want to reconcile from the Account dropdown.
