Well you used "do" correctly above so I assume that's not a big problem but "did" can be used as a question word "did you take out the garbage?" or "did you finish your homework" it can also be used a statement. "I did take out the garbage" or "I did do my homework"
Did is past tense - do is present tense. Eg I want to do my homework today
because I did not do any yesterday.
i do not know how to use embalming in a sentence. (there is the sentence)
So- you are asking when to use 'when' in a sentence. When you are asking how to use when in a question, you are already using when in a sentence, because a question actually is a sentence. I like to use when in a sentence whenever I like.
