This isn't the kind of service I want you to experience, @djcinnovations.
First, let me give you a warm welcome to the Community. I'm here to share a few things about closing an account in QuickBooks Self-Employed.
Once an account has been deleted, this will completely get rid of the data. We usually don't recommend this option if you still need access to your previous bank transactions. You can check out this link for more information: Delete a bank account in QuickBooks Self-Employed.
You can still recover this data by reaching out to our support team. They can help verify and retrieve the information you need in a safe and secure environment. You can get immediate assistance through live chat support. Just click this link for the outlined steps: Contact QuickBooks Self-Employed Support.
I want to ensure you get all the assistance you need, so please let me know how it goes. I'm always on standby if you need further help. Have a nice day!
