I am about to start this cycle

Stats: 38 years old, 5'5", 185lbs, 13.5%bf
current diet: IBW 67kg x 38
2546 kcal
254g carbs / 42g
190g protein /31
84g fat / 14g

I started lifting about 6 years ago. I came from 116lbs. That said, this journey has been like no other.
This will be my first cutting cycle and i was wondering how much carbs/fats/protein you think i should consume. I know T3 is hell on muscle loss, so I want to be sure I don't do too little or too much. Is it ok to eat carbs throughout the day? Cycle carbs?

Though I am around 14% bf, I still have yet to fully see my abs. (i can see them but not how i'd like) 38 fucking years and I think it's about time. Thank you so much for your help. Much appreciated!
