Help With Chromatic Turns

Hi! I need some help with a problem I have. I am trying to arrange Fredric Chopin's Nocturne Opus 9 No. 2 for two guitars. The issue is, there is a chromatic turn (see image below) (I apologize if I did not get the terminology correct, I'm not familiar with turns), and I can't seem to find an option for making it chromatic. Any help is appreciated, and thank you for taking the time out of your day to read this and hopefully help me.
