The 5♣ and 5♦ responses say nothing about the trump queen. The 4NT bidder can bid the cheapest non-trump suit to ask about it.

There are various schemes for the response. The simplest is:

Trumps:   Denies the queen

5NT:   Shows the queen, but no side-suit kings

Side suit:   Shows the queen, and the king of that suit
