Where do I find the business id number for a psychotherapist?

Exactly here do I find the business id number for a psychotherapist in relation to Schedule C/Worksheet/Qualified Business Income Deduction Information #C/Trade or Business ID Number? See attached screenshot? These numbers do not work, in that when I input either number (or our EIN we got from the gov) Turbotax gives a message that "The EIN is not valid."
