Present Perfect Structure - Do not forget it! Both have/haven't and has/hasn't are auxiliary verbs and they are chosen according to the person. The main verb of the sentence is in Past Participle(Third column of the verb table).
Have - I, You, We, They
Has - He, She, It
Positive = Subject(person) + have/has + Main verb(Past Participle) + object(complement)Negative = Subject(person) + haven't/hasn't + Main verb(P. Participle) + object(complement)
Interrogative = have/has + Subject(person) + Main verb(P. Participle) + object(complement)

I've never... She's never... (Eu nunca...)
Have you ever...? Has he ever...? (Você já...?)
I've just... She's just...(Eu acabei de...)
I've been to... He's been to...(Eu estive em...)
I hope y'all have learnt a lot throughout this topic.
