Sorry, your question is not correct. Your first sentence is the only correct option for the question. You can say this: "When the reservation was made, I was asked if I want to pay for breakfast too." Here "when" is not used in a question and so the word order is the same as for other statements. .

It isn't. In English we do not have this kind of flexibility in question forms. Only the first question is correct. I can see from your question that you haven't been taught the basic formula for interrogative forms. This is the standard word order: 1. Question word: When 2. Auxiliary verb: was 3. Subject: the reservation 4. Main verb: made? This is a very simple formula, and it works for all types of questions. You need to learn this 1,2,3, 4 formula and use it whenever you make a question.
