Clear Fill History from Text Input Boxes

I’m using Brave for Mac Version 1.13.86 Chromium: 85.0.4183.102 (Official Build) (64-bit).

On a range of websites, there is collected history of the text I input into each text box, so when I click in the text box to type text (such as a subject to a blog or forum post or a subject to a message), all of the previous autofill history appears in a drop-down menu.

It’s getting to the point where it’s building up on a couple of sites, and I want to be able to clear this.

Clearing Site Data and my Autofill settings didn’t resolve the issue. What do I need to try now?

I can reply back with further examples if need be.

Thanks!
