I have bank data missing from the QB online bank transactions list. I followed instructions for uploading the missing transactions but they are not there - ideas?

Welcome to the Community, @kerdelt.

Let me help and provide information about your missing bank transactions in QuickBooks Online (QBO).

To start, may I know what specific name of the bank? to verify if there are any issues between QBO. If you're unable to find your downloaded transactions in QBO, here's how to check different areas of your accounts to find missing transactions:

Step 1: Get the latest transactions

1. Go to Transactions, then Bank Transactions
2. Select Update.

When it's finished, check the Banking menu again for the missing transaction. It's likely in the For Review section. If the download seems stuck, here's what to do if bank transactions won’t download.

Step 2: Check around the Banking menu

1. Go to Transactions, then Bank Transactions.
2. Select the tile for the bank or credit card account you downloaded the transaction from.

These are the three areas to check:

• Start in the For review tab. This is where QuickBooks puts recently downloaded transactions. If you find the missing transaction, categorize it into an account. Transactions don't show up on your books until you categorize them.
• Next, check the Categorized tab. This tells you what happens to transactions you already categorized. Specifically, review the Added or Matched column. This tells you which account you categorized the transaction into. If you find your missing transaction, but it's in the wrong account, follow these steps to unmatch and move it.
• Finally, check the Excluded tab. If you mark a transaction as personal or a duplicate, it goes here. QuickBooks won't add excluded transactions to your accounts. If you want to include it, select Undo from the action column. Then go back to the For review tab and categorize it into the correct account.
