Yup, and follow the volumes from the fermenter. You put in 19.87 liters, lose 0.95 liters to trub which makes it 18.93 liters total. Now, you have checked off the box to add the starter to the bottling volume. So that adds 2.2 liters giving you a finished total of 21.13 liters. While technically, this volume is added to the fermenter, giving you a total of 22.07 liters in the fermenter once you pitch your starter, the program does not list it this way. The net result is approximately the same though.
Seems pretty straight forward. The program usually has the information available to track back where issues may come from or for the user to compare actual measurements versus estimated ones.
