I want to ensure you have the same balance with QuickBooks Online and your real bank statement.

QuickBooks data depends on how you entered the transactions. All the transactions in your bank statement should match with QuickBooks Online.

Since you have different balances, I recommend checking all your transactions and comparing them with your real bank statement.

Once you find the incorrect transaction, modify it before reconciling the account.

Here's how:

1. From the left menu, choose Transactions.
2. Under the Bank Transactions tab, tick the check box for the selected transaction.
3. Click Edit.
4. Enter necessary details.
5. Hit Apply.
