Hi there,

Is the bank balance shown in QuickBooks, correct? It's good to know you were able to manually record the missing bank transactions in QuickBooks Online. 

Here are a few things we can check when doing bank reconciliation:

• Check the date of the two transaction recorded is correct.
• Check the filter date set in the reconciliation page.
• Check for any duplicate transactions.

I recommend reviewing the remaining transactions to see if they should appear in the bank account you're reconciling. Check those entries from the Bank Register page and compare with your bank statement. This ensures that your reconciliation remains correct.

Here's how:

1. Go to Gear icon ⚙ and select Chart of accounts.
2. Find the account you want to review. Then, select View register in the Action column.
3. Select the Filter icon, then select the filters you want to apply. You can use the Find field to search by amount, reference number, or memo.
4. Select Apply.
5. Locate the two transaction amount, date and see if there is no duplicate, then click it to expand the page.
