Do I need to issue a K-1 Form?

I am filing a final 1041 for my mother-in-law's trust as my wife is the executor/trustee.  My wife, her brother and sister all shared in a distribution from the sale of my mother-in-law's home.  Is there a need for me to issue a K-1 for the wife, brother and sister?  I actually saw the form letter and K-1 in TurboTax Business but it did not have the amount of the distribution they all shared.  Am I missing something here?
