Estate Return Form 1041 Schedule B line 9 (Income Required to be Distributed Currently)

I'm working on Form 1041 for an estate which received a non-taxable legal settlement which was deposited to an estate bank account (no interest) and the money were distributed to the beneficiaries. 

What do I put on line 9 of Schedule B: the amount  distributed to the beneficiaries or zero since there was no income earned?

Thank You.
