California state return

In schedule CA (NR) TT puts a large number in Section B, column C (additions) line 5 which has a huge effect on my taxes. Can anyone tell me where TT gets that number? In the interview TT shows it as "Rental or Royalty adjustment".

I have had a huge help from you experts and can never thank you enough. I am about ready to file. I feel I need to understand that number. The tax is about $3000. more than I think I should be paying for my sale.
