It's never "have". Have is "tener". I don't know where it was said "have". Maybe you had "will have" but it's not for this kind of sentence, it's for another context that I didn't meet yet (remember that the hint word is a dictionary for all the sentences, it's not contextual, and using all the given words in every sentences is wrong)
Querer is to want (or to love if used with a person as the object).
That commonly-repeated advice is wrong. OK, it mostly works at this stage of the course. But it is mostly wrong in ordinary Spanish.
For instance, if the conjugated verb is an auxiliary verb, then the next one is usually a participle, not an infinitive.
Some people try to follow this "rule" later in the course after they have learned the Spanish present continuous and can't understand why they are getting marked wrong.
