Investors & landlords

I received a Maryland K-1 504 but there is nothing reported in the "Distributed Net taxable Income, ..." Section.  I also cannot find the Trusts, Estates, or Partnerships section on the page entitled "Here's the income that Maryland handles differently".  There was only one amount on Federal form 1041 K-1 in box 14, labeled "H".  Does this mean that there is nothing to fill out on form 504, and that is why nothing is showing up?  Please advise, thanks!
