In index.tpl it's only {$HOOK_HOME} and I think it's your center column.
In this hook on index page (in default installation) is home editor module and feature products module.
So if you need adjust center column at start page (index) so you need edit modules/editorial/editorial.tpl and modules/homefeatured/homefeatured.tpl
If center column from product page edit - themes/prestashop/product.tpl
and so on
