Help with Calculations

I'm getting a little mixed up in some of the calculations needed to set my goals on my profile and in turn chart my eating and progress. I read the sticky on how to calculate your TDEE etc but my numbers didn't match up.

I am struggling to make my calorie count each day I've tracked so far and I read a post that if I have already set my calories at -20% I shouldn't follow them. I am gearing up to move from doing insanity to P90X in coming weeks that says my macros should be 50/30/20.

Can someone please advise where my I'm going wrong on my calculations please?

Current weight: 71.1kg
Target weight: 65kg
Height: 166cm
Age : 29
Sex: Male
Weekly weight loss target: 1lb/ 0.45kg

Workouts per week: 5-6 at 45 mins
TEF: 3500 cals per week
Sedentary Activity (Desk Job)

Not sure what else I need to provide to calculate?

Any help appreciated, thanks
