Who to cut to bring CMC back off IR?

Probably one of the QB or Dawson Knox

First, cut Knox. Second, trade one of those backup QB’s for a top TE or RB. You don’t need 3 QB’s in a single starter league, and you could find an upgrade to Mark Andrews or your RB position.

Assuming this is a 10 or 8-team league based on the lineup. Knox or Cooks can be dropped, but I agree about trading one or 2 of your QB’s. Maybe package Andrews and a QB to try to get a Waller or Kelce (not likely, but you can try).
