Tun deadspace

I'm using BeerSmith 2.3.7. Were do I enter the volume for tun deadspace? Searched online and found "In the equipment profile". Unfortunately, not seeing a "tun deadspace" in the equipment profile.  I do see "Lauter Tun Losses". Is this the tun deadspace setting?

Thanks.

Yes, this is where you would enter the mash tun/lauter tun dead space value(s).
