Answer 2

✨The sentence, “I had done it” is a positive statement, therefore the question tag has to be negative question tag , thus we write, “I had done it, hadn't I? If the sentence were negative we would write, “I hadn't done it, had I? Thank you for your question. The answers you have gotten are all great.✨
