Hi there, @chris231.
Thank you for posting here in the Community. Let's get you over to the phone support team to restore missing transactions in QuickBooks Self-Employed.
I recommend contacting our QuickBooks Support Team regarding the deleted bank transactions. One of them will be able to check the issue further and determine if they can retrieve it using the tools in a secure environment.
Before you proceed, please make sure to reconnect your bank first from the Bank accounts page. This way, the representative will be able to assist you right away.
Here's how you can reach them:
- Click the Help option in the upper-right corner.
- Select Contact us.
- Enter your concern, then press Continue.
- Choose Start a chat or Get a callback.
For additional reference, you can use the following article to import bank transactions manually in QuickBooks: Manually import transactions into QuickBooks Self-Employed.
I'm always here to help if you need anything else regarding the missing data in QuickBooks. Enjoy the rest of your day.
