I talked to a Lacerte 300 user and this was what I was told.  No idea if this addresses your question.

In the 2021 Lacerte tax program, each time he did a Form for a new client, Lacerte would ask him to confirm (and that one credit would be used up).  It then told him how many credits he had left.  Between that and the list pointed out by George, there would be your tracking, I guess.
