Let's get your missing bank transactions added to QuickBooks Online by updating your account manually from the Banking page. Here's how:
- Sign in to your QuickBooks Online (QBO) account.
- Click Banking/Transactions from the left menu.
- Select the appropriate bank account, then select Update.
Once done, go to the For Review tab and check the missing transactions from there. If you get the same result, you can read this article for more troubleshooting steps: What to do if you can’t find downloaded transactions in QuickBooks Online.
Additionally, if this is your first time connecting your bank account to QuickBooks the transaction will be downloaded depending on the number of days your bank allows. Some banks allow 90 days others up to 1year.
Additionally, you can manually upload the transactions using a CSV file. For the detailed steps, see this article: Manually upload transactions into QuickBooks Online.
