Sometimes English speakers ask "Did you ___?" when they really mean "Do you ___?" For example:

Did you want to talk to me about something?

Grace, did you have anything that you wanted to add?

You can ask a question this way when you're asking about something that a person was thinking about or wanting. That's because they started thinking about it before you asked the question.

"Did you ___?" has a little bit of a softer sound than "Do you ___?" You're most likely to hear this kind of question in professional situations.
