If, during the enchanted player’s declare attackers step, a creature they control is tapped, is affected by a spell or ability that says it can’t attack, or hasn’t been under that player’s control continuously since the turn began (and doesn’t have haste), then it doesn’t attack. If there’s a cost associated with having the creature attack, the player isn’t forced to pay that cost, so it doesn’t have to attack in that case either.

The enchanted player still chooses which player or planeswalker each creature they control attacks.
