Weight loss plan

Hi. I am 26F, 5’4 and around 140-150 pounds not exactly sure but pretty close to that. My activity level is moderate: sport for 30min to an hour on average every day +walking at least 40 min in total during commute and errands etc but I have a ´desk job’ you could say. Also whitout being super muscular, I do have a good amount of muscle especially in upper body that have been maintained for years and years now.

I want to go back to a lower weight and plan on eating everyday:
-around 1300-1400 kcals
-the split being 118 P, 170 C and 26 F
I know it seems way to precise but I tend to eat thé Same things everyday which is then easy to calculate.
Just want a bit of confirmation that I would lose this way. Thank youuuu
