I appreciate you trying to find the missing bank transactions in your way. Allow me to share some information and help you resolve this issue.
You can start to refresh your bank account manually. It can help bring the transactions back.
Here's how:
Go to the Gear icon.
Choose Bank accounts.
Click Refresh all.
You can also check if the transactions are already in your QuickBooks Self-Employed account. Follow the steps below
From the left menu, click the Transactions tab.
In the Type drop-down, select All.
Choose your bank account from the drop-down, and change the Date to All.
If you still can't see the missing transactions, it is best to contact our QuickBooks Self-employed support team. They have tools that can pull up your account in a secure environment and check the cause of this odd behavior. They can also perform other troubleshooting steps to fix this for you.
