what is the right verbal tense to use?

Hello there, well I can't say your examples are wrong, the first one makes sence to me I can't say the same about the second one though. I have some examples:

1- do you have the documents (with you)?
2- did you bring the documents?

One more thing I noticed, I'm almost sure is grammatically incorrect when you said "I've a question" the correct way would be "I have a question". We don't abbreviate the word "have" when we're talking about owning something for example I can't say "I've a car" the correct way is "I have a car". We can only abbreviate the word "have" when we're using it as "present perfect" like "I have been here before", "I've been here before". I hope I've been of some help
