Sure, I can help you with that! Here's how you can update your table of contents to include Heading 4, 5, 6, and so on:

1. First, make sure that your headings are formatted correctly. Heading 1 should be used for the main title of your document, Heading 2 for major sections, Heading 3 for sub-sections, and so on.
2. Next, place your cursor where you want to insert the table of contents.
3. Go to the "References" tab in the ribbon at the top of the screen.
4. Click on "Table of Contents" in the "Table of Contents" section.
5. Choose "Custom Table of Contents" at the bottom of the drop-down menu.
6. In the "Table of Contents" dialog box, make sure that the "Show levels" field is set to the number of heading levels you want to include in your table of contents (for example, if you want to include Heading 4, set it to 4).
7. Click "OK" to insert the table of contents.
8. If your headings are already formatted correctly, the table of contents should update automatically. If not, you can update it manually by right-clicking on the table of contents and choosing "Update Field" from the drop-down menu.

That's it! Your table of contents should now include all the heading levels you want.
