I'm having a really hard time plugging in a diet to meet these macros I've come up with (not even sure if they're 100% correct). I've been working out for about a year. 6 times a week heavy lifting, I also do cardio for about 30 mins everyday. Here are the stats I'm able to provide of myself.

5'8" = 173cm = 68"
178.5lbs = 81kg
34.5" waist at navel relaxed
15.5" neck
39.5" hips
12.5" forearm
7" wrist
Body Fat = 18%
Fat Mass = 34 lbs
Lean Mass = 144 lbs

So, plugging this into a few TDEE calculators I've come up with an average.

TDEE = 3230

Now I'm subtracting 20% for my deficit(is this enough?)

3230 - 20% = 2422.5

Then using a 40/40/20 for daily intake (is this right?)

40/40/20 = 969/969/484.5

242.25/242.25/53.8

Then I'm slightly altering to try and come up with a difficult diet.

protein = 300g carbs = 200g fats = 45g

And this is where I've been stuck for the past 2 days. I'm trying to plug in foods to reach this daily amount (eating every 3 hours). It looks something like this;

08:00am - Meal 1: 50g protein, 100g carbs, 10g fat

11:30am - Meal 2: 50g protein, 7g fat

02:30pm - Meal 3: 50g protein, 50g carbs, 7g fat

03:30pm - Workout

04:30pm - Meal 4: 50g protein, 50g carbs, 7g fat

07:30pm - Meal 5: 50g protein, 7g fat

10:30pm - Meal 6: 50g protein, 7g fat

Any advice would help.
