In v24.01, there is a new tool for the Timeline called Rectangle Selection. Maybe that’s what’s confusing you.
You can turn it OFF in Settings > Timeline
But regardless of whether it is ON or OFF, you can always move the Playhead with the mouse. I don’t use a stylus, but I guess it works the same…
Just hover your mouse (or stylus) on an empty part (no clip) of the timeline until you reach the Playhead. The mouse cursor will turn into a double arrow
Grab the Playhead and move it to it’s new position.
