Business & farm

Okay so I will put the 79,000 which is the total NOL from the previous years carried forward since I had never used it. I don't have to though right? I can just keep carrying it forward? 

But if I do use it, if at the end it says my income is negative 34,000 now is that what I would put next year as my NOL? I tried to read the publication but I need a for dummies version..
