Where is this CSS located?

[NazeeshKha30d1]

I'm trying to change the minimum height in the following CSS:

But I cannot locate the CSS. When I check link under ".(index)1651" it points to https://domain.com/checkout/cart/:1651

I tried adding the CSS class to a CSS-file, but it gets disabled and the CSS in the screenshot keeps being used.

I have the shop in developer mode.

Any idea where I could find this CSS?
