Impossible to find translation

[Higino]

Hey friends, 
 

I know there are already a number of topics about this, but my problem seems to be different.

I'm trying to translate the text that says "Tax included" on the product page. I'm using a theme called Metro Market. My Prestashop version is 1.7.7.4. 

I've looked in International > Translations > Theme > classic and metromarket. I've tried both.

I've also tried the shipping price manager module, and looked around in other places. When I search for "tax" and "iva", no results that match the field I'm looking for.

For future versions please consider just making a global search box to look for translations on the whole thing instead of having to check every single module and theme.
