Thanks for being a part of the QuickBooks family, bushy402.
I'd be delighted to address your concern in regard to disconnecting a bank account.
Removing an account in QuickBooks Online won't delete the transactions associated with it. You'll need to open each and manually delete them one at a time.
Once done, you can proceed with disconnecting the bank account. Please refer to the steps below:
1. Click the Banking menu from the left navigation panel.
2. Choose the Banking tab at the top of your screen.
3. Select the account you want to change, then click the Edit (pencil) icon and Edit account info button.
4. In the Account window, select the Disconnect this account on save checkbox.
5. Click the Save and Close button to finish.
Note: (UK banks only) If you disconnect or delete a direct feeds account for a bank in the UK and you want to reconnect it later, you'll need to complete all the connection steps again. This includes reauthorizing the bank by completing, printing, signing, and posting the authorization form.
After following these steps, I'm confident that you'll be able to disconnect the specific bank account and start fresh.
Feel free to post again in the Community if you need more help. I'm just a post away. Have a pleasant day ahead!
