Bonjour
1- Has Jim sold his old computer ?
2- Have they listened to the concert ?
3- Has my sister written several novels ?
4- Has Jenny decided to stop smoking ?
Tes phrases sont au present perfect. À ce temps, inutile d'utiliser "do" or "did". On inverse simplement have et le sujet.
À la forme interrogative = "have/has" + sujet + participe passé
À la forme négative = sujet + "have/has + not + participe passé
