I am not doing this correctly, aren't I?
We can certainly help. You're the one who's building a wizard, right?
OK, let's start from the top. You pretty much have everything that matters already it's just a matter of figuring out some numbers based off of what you already have.
Fill in the player as "Pencil_Art" and the campaign as "Saving Sandiron".
You need a background. Your ideal of Beauty was taken from the Sage Background, so you likely want to be a Sage; your short backstory suggests "Sage (Researcher)". This goes in the top of your sheet. It also grants some starting equipment if you didn't roll for weath, and also grants some additional proficient skills (Arcana and History, which you already have; see below)
Alignment of Good is Good, but are you Lawful Good (LG), Neutral Good (NG) or Chaotic Good (CG)?
Wizards have 1d6 hit dice, and you have a +2 constitution modifier from having 14 CON (14-10=4, 4/2 = +2), so your starting max for first level HP is 8. Not sure where 20 came from, but it's where your current HP goes, max HP is just below that.
Your Stat mods are Str 0, Dex 0, Con 2, Int 2, wis 1, Cha 0. You currently have recorded Str 0, Dex 2, Con 0, Int 1, Wis 0, Cha 0.
Your skills; your background (assuming you picked Sage) gives the same ones you picked from the Wizard skill list, so pick two more from Insight, Investigation, Medicine, and Religion. Also, from being an elf you have proficiency in Perception.
The saving throws beside Intelligence and Wisdom should be checked off, from your wizard class. This makes your save numbers for them 4 and 3 respectively; the numbers for the rest of them are the same as your mod for them (Str 0 Dex 0 Con 2 Int 4 Wis 3 Cha 0)
Your speed is 30 feet for being an elf. This goes under Exploration, with Passive Perception, which for you is 13 (proficient at perception and a +1 wis mod means 10+2+1).
Under Features and Traits, instead of your backstory you need your class features, background feature (Researcher for Sage), and racial traits. Your backstory can be moved down to Other Notes. The text block should look like this:
Darkvision 60 ft (Racial)
Keen Senses (Racial)
Fey Ancestory (Racial)
Trance (Racial)
Bonus Cantrip (Racial)
Researcher (Background)
Spellcasting
Arcane Recovery
You should have a 4th cantrip known from your high-elf race.
Your casting ability is 14, Save DC is 12, spell attack bonus is +4
And that's it. You still need a description, personality, and other flavorful things down below those, oh and clothes you're currently naked, and I need to check your equipment later, but those are all the most important things.
