How to get all Atlas Boss points?

I just had the same problem. Go to ur atlas points and hover over the counter for the boss points. It will show u what the 5 things are but unfortunately it doesn't highlight which one u r missing.

You need to finish a lvl 80+ map with 6 mods. So just running a T15 isn't enough. You need more area lvls on top.

I am doing lvl 81 with 7-9 miss no review Maps. +1 from corr map and irr. Map was with powerfull boss sign.

You need a 6 mod citadel boss

Need a 6 mod t15+ kill on an anomaly boss (the ones that drop the unique support skills)

There is a mobalytics guide about it (just saying for future similar questions 😊)
