Can you apply metamagic on the Wish spell? For example using Twinned Spell on Otto's Irresistible Dance cast through Wish?
This is specifically addressed in the Sage Advice Compendium:
Can my sorcerer use Twinned Spell on a spell duplicated by the casting of a wish spell? And if so, how many sorcery points does it cost? Yes, you can. It costs the number of sorcery points appropriate for the level of the spell you’re duplicating.
