Based on the latter part (paragraph) of your explanation, I think I got it. (We do) enter the NOL that will be carried back or forward depending on the situation on line 21 going forward. The software was doing that, but I wanted to be absolutely sure that it was calculating properly -- with a current year loss (1040, line 12) and a "cumulative" current forward of NOL on line 21 for following year amount. I was just not sure if the cumulative amount was supposed to appear on line 21.

Thank you.
