Retirement tax questions

Follow on question for me - why is "Amount to be Contributed by Plan Due Date" Red?  Do I need to take that amount back? This case seems to be like this.  (Numbers only example, actual number are different) 1) Net Income : $80 ;  2) Contribution $100.  So it says "Amount to be Contributed by Plan Due Date" = -$20.   What do I need to do? Take that money back from 401k?
