Ways to tell them apart:
Have not is a contraction version of have not, so remember have comes first, indicating possession or auxiliary use.
Do not have uses do not to negate possession, introducing an action or state without possession.
The word do in do not have indicates a focus on the action or lack thereof, whereas have not emphasizes the state or result of having.
