If you've beaten:

Hydra in olympus (required)

Storm rider in Lod visit 2

Groundshaker in Pride lands visit 2

you should have it

This, the Kh wiki says the same thing:

Kingdom Hearts II

Thunder: Defeat the Hydra (Olympus Coliseum).

Thundara: Upgraded after the defeat of Storm Rider (Land of Dragons).

Thundaga: Upgraded after the defeat of Groundshaker (Pride Lands).

 

If that doesn't work you're gonna have to wait until 2.5

Do you currently have Thunder or Thundara?  Also, it looks like you get Thundaga upon your second visit to the Pride Lands and defeated an additional boss.  So, if you haven't been there twice, chances are you haven't defeated the Groundshaker yet.

I already discussed it with you in the chat, but i'm just gonna put an answer

Since you already reached TWTNW, and defeating Hydra and Storm Rider is mandatory, you haven't defeated Ground Shaker, since the visits to Pride Lands are both optional. So defeating it will reward you with the Thunder Element, and you'll get Thundaga.
