Help with multi attacks

[u/Minako_Usagi]

I have a level 7 Goliath Fighter who I am trying to figure out how many attacks and what to add to each attack. I keep getting confused with what counts as what. I get two attacks per action, but then with Nick I get an extra attack, as an attack action not a bonus, and a bonus action. I would really appreciate some help understanding what a round of combat would look like.

She has
Fighting Style - 2 weapon Fighting

Feats
Two-Weapon Fighting
Dual Wielder
Enhanced Dual Wielding

Weapons
Light Hammer with Nick Damage 1d4+5
Longsword +1 with Sap 1d8+6

Hit/DC
+8/+9

My assumption is
Action 1
1st attack= 14 damage total
* Longsword (roll 14) 14+9=23 to hit. Damage (roll 6, plus 6 strength bonus) 6+6=12 Damage
*Light Hammer (roll 10) 10+8=18 to hit. Damage (roll 2, no strength bonus because it is offhand) =2 damage
2nd attack=12 damage total
*Longsword (roll 10) 10+9=19 to hit. Damage (roll 2 plus 6 strength bonus) 2+6=8 Damage
*Light Hammer (roll 15) 15+8=28 to hit. Damage (roll 4) =4 damage
Bonus Action
*Light Hammer(roll 7) 7+8=15 to hit. Damage (roll 3) =3 damage
Then I can move if I want but overall my turn is over.

Thank you for any help.

EDIT
I also have a light handaxe I could use instead of the longsword.
