I was interested in updating this link with a little more detail:
https://gamesx.com/controldata/turbocont.htm
I remember there used to be wiki options and such.
That page needs a bit of an update, for sure.
But for now, you can start with the wiki: https://gamesx.com/wiki/doku.php?id=controls:controller_data
Ah, there is the link I was looking for. Thanks Lawrence!
