How does the skills section work?

I’m filling out the a pdf character sheet for my character who is a high elf wizard and I’m not sure how the skill box works. I’ve got all my saving throws done but I’m really just confused with the dots down the side.

Which dots do I fill in and how does that change the number beside it?

If this helps my saving throw totals are:

  • +1 Strength
  • +4 Dexterity
  • +1 Constitution
  • +6 Intelligence
  • +3 Wisdom
  • +3 Charisma
