Hello, @getrung,

Let's fix the incorrect opening balance of your personal checking and savings accounts.

These accounts might have reconciliation discrepancies since they show different balances in the next reconciliation. Reconciliation discrepancies are caused by:

• previously reconciled transactions have been modified, deleted, or added.
• reconciliation adjustments, such as Journal entries.
• possible data damage
• no balance or an incorrect balance was entered when the account was set up.

To help you identify discrepancies, you can pull up the Reconciliation Discrepancy report. This reports shows transactions sorted by statement data that were changes since the last reconciliation.

Here's how to run the report:

1. Go to your Reports menu.
2. Select Banking, then Reconciliation Discrepancy.
3. Choose the appropriate account, then click OK.
4. Review the report to identify ant discrepancies.

You can also open your Missing Checks report to help you verify missing transactions. Or open the Transaction Detail report to verify transactions that were changed or modified. Once a discrepancy is identified, you need to make the necessary corrections. 

For additional guidance with the solution above, you can go through these articles:

• Zero or incorrect Beginning Balance in the Begin Reconciliation Window.

Please keep me posted on what the results are and I'll get back to you with the information you need.
