Everything not in the primary storyline is connected to something in the primary - as indicated by these vertical "stems":

You have a secondary storyline, where are adding this "Pickleball" clip.
A secondary storyline is magnetic, like the primary, but the rest of the clips
are connected to the primary, not the secondary.
Perhaps you want to reorganize your timeline in a different way - so as to make what is now a secondary
storyline your primary.
This may not be too hard to do, but for safety, start by doing this:
0 - Make a snapshot of the project, so you can return to the present point if things go out of hand: to do that, select the project in the browser, control-click, Snapshot Project.

1 - Select all the audio clips in the primary storyline, and press Command-Option-UpArrow to "lift from storyline".
This will make them connected clips, and put a gap clip (essentially a slug or placeholder, an "empty" clip) in the primary
2 - Select the secondary storyline and press Command-Option-DownArrow to "Overwrite to Primary Storyline".
Now those clips that were in the secondary are on the primary.
The only thing you need to consider now is where are each of the connection points.
Anything that is connected to a place after the insertion point will shift automatically.
