If morality is just whatever is returned by the algorithm in your mind that makes moral judgments, then when that algorithm returns a result "no result" that is itself a result -- what is there you do not know about the subject?

If the algorithm in my mind returns "gee, I'm not sure... there are wrong things about X, and there are right things about X, and mostly it seems like I have to think about it more in order to be sure," one possible interpretation of that result (and, in fact, the one I'm likely to provisionally adopt, as in my experience it often turns out to be true) is that if I think about it more, and more carefully, I will know more about my moral judgments about X than I do at that moment.

Sure, it's possible that this is confabulation, and that what I experience as "not knowing what my judgment is" is really "not having yet made a judgment". I'm not sure that distinction actually matters, though.

Note, also, that there is a difference between what I said (that morality is "an algorithm in my mind") and what you said (morality is "whatever is returned by the algorithm in your mind"). I don't know if that distinction matters, either, but it seems related... you are focused on an answer to a specific question in isolation, I am focused on the process that generates answers to a class of questions, often over time.
