Explicación:
Por lo que entendí lo único que tienes que hacer es poner el verbo auxiliar "Do" o "Does" que depende de la persona a la que se refiere. Y el verbo "have", el cual en ésta situación no se conjuga con tercera persona, ya que, se esta usando en auxiliar "Do" o "Does" los cuales reemplazan esa función. Dejé dos posibles respuesta, afirmativa y negativa. Por último en la respuestas puedes elegir si usar "doesn't" o "don't" en vez de "does not" o "do not".
Fórmula:
Tercera persona del singular:
Does + subject + main verb (have) + complement.
Demás personas:
Do + subject + main verb (have) + complement.
Espero haber sido de ayuda.
