Moving from autonomous/IC to management

I used to have a very autonomous individual contributor dev/dev advocate role and a few months ago moved to management. The switch has proved extremely overwhelming as the nature of the job is now radically different, even though I'm managing the team I used to be on. There are many more meetings, many more admin tasks, and a lot more overall chaos in my schedule. Do you have any advice on how to adapt systems for this kind of change? I'm not sure if Rose has ever made this change, but I know she's also gone between "indie" and "jobby job," which seems similar to experiences Scotty may have had moving to management. Thanks!
