New Post: VAT total line in checkout

Hello,

there is a tax summary line in the checkout which shows the total amount of tax included (VAT in my case); however, in a consumer environment it is a bit confusing and I would like either remove it or change the text to explain that it is not extra cost etc.. Is there a way to customise that, please? I found no template addressing that and no class either, if I am not mistaken.
Please note that I am not referring to the tax number which can be disabled on the checkout module settings.

Thanks a lot!
