How to rename the word ‘Tax’ on ORDER SUMMARY to ‘Estimated tax’?

Magento 2.4.2-p1
Smartwave Porto theme
extensions from Amasty

We need to rename the word Tax on ORDER SUMMARY from ‘Tax’ to ‘Estimated Tax’. I was able to change the one below (which appears when you click the arrow) in Stores --> Taxes --> Tax rules --> Tax Identifier = estimated tax but not the one above.

I even tried:

Stores > Configuration > Developer > Translate Inline

But it’s not one of the words that can be changed via this process.
