Listing children terms in each term page

I'm a total novice at Drupal so apologies for being an idiot. I've created a taxonomy tree like so,

-brand1
--cateogry1
---product1
--category2
-brand2
--category1
--category2
---product1
---product2

And I have created a separate menu bar using "Taxonomy Menu" module. What I need here is a page for every link (terms) given above. By default when a link is clicked from the menu it shows an empty page. The page of a term needs to list all it's children but not it's grandchildren. E.g, clicking brand2 should list category1 and category2. How do I go about doing this? Doesn't matter if I have put some code to make this work.

I've also tried making a view for this but I just can't get to achieve what i need. Do I have to make changes to the "Taxonomy Term" view that is there laying disabled?

Please help!! :,(
