Funny ... after waiting and waiting for the form on a $8800 NOL from 2023, ProSeries didn't even produce the form. The diagnostic was cleared and it allowed me to electronically file without it.

I believe the form is to compute the current year NOL. When you go in and force it to populate, it puts the data for 2024 in. 

Thus, the second page is for those lucky few that can carryback a NOL 2 years (primarily farmers). The second page is for computing the amount absorbed in the year 2 years back, carrying the balance to the year 1 year back, and computing if there is any leftover to carryover.

For carrying a loss from 2023 or earlier into 2024, the form apparently is not required by the IRS. It seems to be only required for 2024 losses and forward.

If anyone has a different idea, please post it.
