Good day, Delcodoula. I'll help you in viewing your data.
The read-only access to financial data is only applicable to QuickBooks Online. In QuickBooks Self-Employed, we need to have an active subscription so we can view the data of your self-employment.
What I can suggest is to temporarily reactivate your subscription to get the details you need. Once done, you can cancel it again.
I've added these articles for additional details. You'll get more information about exporting transaction:
Please comment below if you have other questions. I'll be glad to assist you.
