Thank you for your help but I have left out the year for 2018 Can you help with this one?

Question: I just need help in understanding where to figure out amounts.  I have watched video's, used power points and I am missing something.

Can  you help me with this problem below?
I am more of a visual learner.  If I can get the formula's I can do the work.  I have part of this, but I am not getting the remaining, trying to get the carryforward and carry back.
I am willing to take a deduction  for turning it in late, if I can learn how to compute this  problem and get the correct answer.  Its due tonight.
Thank you
Coralee
