Let me share some information on how to get your company ID, @Tvnews. 

You can get your company ID from the payment receipt that you'll be receiving from Intuit every month for your subscription. 

That'll be sent to the email address associated to your QuickBooks Self-Employed  account. 

For other concerns about your account or anything else, let me know by leaving a comment below. We're always here to help. Have a good day!
