It's suggested to download the information first before unsubscribing to QuickBooks Self-Employed (QBSE). If you haven't done so, you can retrieve your previous records by resubscribing to your account.
Once it's active, your old data will now be visible for you to access. If you need further assistance getting the details you need, I suggest contacting our QuickBooks Self-Employed Support Team.
Click the QB Assistant at the top.
Type in the chat box contact support.
You'll now be provided options on how would you like to connect to them.
