NOL Carryforward for Individuals - HELP

[ElizabethP47]

Situation:  I have a client that ran a trucking business for a number of years and in 2022 exited the business due to the economy.  Once calculated, he has a $19k NOL Carryforward.  During the time of trucking, he was single.  In 2023 he got married and now will be filing jointly.  In 2023 he worked only W-2 jobs.

According to 536, he can only claim 80% of the excess of taxable income computed without regards to the NOL.  What does the publication mean by "excess"?  I also understand that this computation can only be done on his income. not joint. 
I just need help with this computation.  Also, what is appropriate to attach as a statement that shows the facts of this NOL?

Thank you so very much, in advance, for anyone's help.

It's the amount that exceeds taxable income after having been zeroed out. There's a good explanation and graphic at the site below.

@tagteam Yes, I understand.  I do use ProSeries but I am trying to guide my client on how to do it on their own without stepping out of bounds with my tax preparer obligations.  I need to understand the mechanics behind it myself before I go and try to explain it to anyone else.

Thank you for your help.

I understand, but you know they have a forum, right?
