to have generally functions as a normal verb and so uses do and does as its auxiliaries. Contracted forms (I’ve, we’ve etc) are usually followed by got, which indicates possession only.
got is only required to indicate possession, but is not necessary (I’ve got a car = I have a car). got cannot be used to indicate habits and activities such as I have got a shower every morning.
the contracted forms I’ve, she’s, they’ve must be just with got to indicate possession (she’s got a dog, not: she’s a dog), otherwise the full form should be used (she has a dog).
got is not generally used in the past. The past is had (+), didn’t have (-), did you have (?), just like any other verb. Examples: I had a dog. I didn’t have a dog. Did you have a dog?
In short answers, never use the contracted forms. Have got a car? Yes, I have (Not: Yes, I’ve).
