Irrevocable Trust withdrawal by Grantor

The irrevocable trust states under a section titled "Payment of income and principal" that the trustee shall pay me (my Dad) as much of the income and principal as I request in writing.

How is this reported on the 1041. Is it considered "other income" and a 1099 is issued? 

In Turbo tax where is the deduction shown. The Trust should not be taxed as my Dad will be.

Any insight is appreciated.
