For dext/ReceiptBank I get the prompt"To use your existing account with Intuit login please link it from the SSO section accountsettings in QB." Where is the SSO section?

Glad to have you here, jmbeninger-gmail. 

The SSO in QuickBoks Online (QBO) is for Google SSO. If you're trying to link a third-party application in QBO using SSO, I can route you to our developers so you'd be guided in accessing your account.

Here's how:

1. Go to https://help.developer.intuit.com/s/.
2. Select API Docs & Tools.
3. Choose QuickBooks Online.
4. Hit Ask a Question.

You can also visit our QuickBooks API Blog to get recent news and updates about this topic.

Don't hesitate to reach out to me if there's anything else that you need help with.
