I have a coworker who consistently says they are "turning comments" to mean "responding to feedback." In particular, it comes up in code review. Someone makes a comment, and the conversation has to be resolved before submitting. This person will say "I spent the day turning comments."
I had never heard this usage of "turn" before, nor had I heard the bigram "turn[ing] comments" used. I am struggling to find any similar usage on the internet either.
I assume that they did not just make this up...but I can't find which field or context they may have borrowed the expression from.
