É muito fácil, vou tentar te ensinar para você usar sempre.
Quando um verbo não é flexível precisamos usar o auxiliar "DO e DOES"
O Do se usa para "I, You, We, They" e o Does se usa apenas para a 3° pessoa do singular que é "He,She ou It". Para fazer uma pergunta e o verbo não é flexível você vai usar os auxilares. Exemplo: Does she have a car? (Ela tem um carro?) / Do you have a car? (Você tem um carro?)
O Did é usado da mesma forma sendo que é o passado.
