Hello there, @Carrera09s.

I'm here to assist you in fixing the opening balance so you can reconcile the next month's statement.

When you reconcile an account, you check the beginning balance in QuickBooks. It is the amount at the start of the period under consideration.

The beginning balance amount should correspond to the amount on your bank statement for the same start date. Having said that, you can correct the opening balance by entering the balance of your actual bank account.

At the start of a bank statement, you must enter the opening balance. Then go through the following steps to go over it:

1. Choose the Accounting menu, then Chart of Accounts.
2. Locate the account in the list.
3. Choose View register.
4. Find the opening balance entry. In the Account column, it should say "Opening Balance Equity."
5. Keep track of the date and the balance.
6. Then, compare the opening balance to your actual account balance.
7. Log in to your bank's website or locate your most recent bank statement.
8. In QuickBooks, look at the account balance for the same day as the opening balance.
9. Examine the two balances.

If your QuickBooks opening balance does not match your bank records, here's how to fix it:

1. To expand the view in QuickBooks, select the opening balance entry.
2. Edit the balance in the Deposit column to match your bank records.

I added this article for more information:  Fix issues the first time you reconcile an account in QuickBooks Online.

After you've adjusted the opening balance, you can begin reconciling the next month's bank statement.

These steps should work fine. Please let me know if you have any bumps along the way. If you need me, I'm only a post away. Have a wonderful day!
