Schedule K-1 (1041)

I have entered the data in Turbo Tax and I have net Long term capital gains yet when I see the summary the amount reportable appears to be zero.  I have $ amounts in 4a and 12.  I don't want to not pay the taxes I owe. The instructions are vague.  How do I know if reporting correctly?  This is from the sale of my parent's house. Thank you for any guidance/clarification you can provide.
