Leak onto the Driver's floor board

I have a 2020 TRD Pro and for several months now I have had a small leak coming from somewhere under the dash on the driver's side. I can't locate it and I can't seem to figure out what exactly is leaking. I thought it was brake fluid but I've marked the reservoir and the level hasn't moved.
Has anyone else experienced this or does anyone have some suggestions as to what it might be?

You're sure it's not brake fluid? It's got a pretty distinct smell.

 

check and mark coolant levels,, I really hope it's not a heater core leak, or I hope you have a warranty.
Also check for debris under hood, up on the cowl, and see if the two side are clogged.
