If the verb is 'have', you usually put 'do', 'does', or 'did' after the subject, followed by 'not' or '-n't', followed by the base form 'have'.
You can simply put 'not' or '-n't' after the verb, but this use is less common.
If you use 'have got', you put 'not' or '-n't' after 'have', followed by 'got'.
