Missing screw? Torx 20

[t6.1]

I found a screw near the front passenger seat on the floor. Any idea where it came from?

If it helps, it's a Torx 20.

I thought I'd found it straight away at the back of the front passenger seat. There's a hole there, but nothing to screw into:


All 3 screws for the glovebox appear to be there.


Not immediately concerned, but it would be nice to know
