Cannot delete transactions in QBSE

You have me to help you delete the transactions, MattLewis.

Let me guide you with these steps:

1. From the Gear icon, select Imports.
2. Locate the bank account with the imported transactions.
3. Under ACCOUNT NAME, click the bank's name.
4. In the Files imported section, click the delete (trash) icon.

If you want to categorize other transactions, you may check this reference: Categorize transactions in QuickBooks Self-Employed.

I'm just a post-away if you need help. Keep safe!
