toc anchors scroll down too far past heading

I have a TOC installed at sab.davidscottlynn.com … I’m using the Gutenberg Block Editor.

TOC works fine EXCEPT that clicking on any heading within the TOC menu scrolls down slightly PAST the heading of each section. So the visitor cannot see that they are at the correct location unless they scroll back up a bit. … But that is NOT necessarily intuitive for them.

I’m familiar with Basic HTML, not much with CSS. But I tried to find some code in the Code Editor that I could move up a bit, to the bottom of previous section, so the Title would be fully visible. That worked for me when I put in my own TOC anchors on a different WordPress website (without a plugin), but I do not see how to do that at this site.

Any Suggestions, Please?

Thank You Very Much,
David Scott Lynn
