Good to see you here in the Community, @Amycao.
Let's get your missing bank transactions added to QuickBooks Online (QBO) by updating your account manually from the Banking page. It will help refresh the connection between your bank and QuickBooks.
Here's how:
- Go to the Banking or Transactions menu.
- Select the bank account with missing transactions.
- From the top-right of the page, click the Update button.
Once done, check your missing transactions from the For review tab. If they still aren't showing, check out this article for other troubleshooting steps: What to do if you can’t find downloaded transactions in QuickBooks Online.
I'd also recommend reaching out to your financial institution. There's a possibility that the connection between your bank's website and QuickBooks was interrupted.
If none, we can manually upload bank transactions into QuickBooks through a web connect file. You can visit this link to check the format of bank transactions in a CSV file: Format CSV file in Excel to get bank transactions into QuickBooks.
