place toc perticuler position in a post about jekyll-toc HOT 1 OPEN

I am looking for a solution to a similar problem as well. By some googling, I figure out that I can separate the "excerpt" and the "rest content" using the Jekyll variable and liquid filter. Here is the solution for me:
The post.html in _layouts folder:

 <div class="entry">
    <div id="markdown-content">
          {{ page.excerpt }}
    </div>
    <div id="table-of-contents">
      {% toc %}
    </div>
    <div id="markdown-content">
          {{ page.content | remove: page.excerpt }}
    </div>
  </div>

A 2019-08-23-hello-world.md in _post folder:

---
layout: post
title: "Hello world! this is a testing post to the new layout!"
tags: [dev]
excerpt_separator: <!--more-->
toc: true
---
this is a short caption for this post 

try this out !
<!--more-->
## Hello world!
this is the first post in my new website for completely free!

this is an empty page for testing.

Then I got:

I think this solves your issue. Sorry for the late late late reply.
