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

[Clayo]

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."

Please re-read my question and *additional* comment and additional screenshot.

You can find the list of business codes used for Schedule C on page 17 & 18 for the 2018 Instructions for Schedule C.  The link below is to the instructions for 2018 Schedule C.  If you do not find an exact match you may use a code that is similar to your profession

Please note that two of those numbers were kicked back by Turbotax and I've attached a screen shot of the kickback.

Do not enter the business code with a 'dash' enter as 642100

I didn't enter my business code with a dash but Turbotax added a dash. Now what?
