Where do I enter my 1099-R on my 1041 estate trust return?

I am filing an irrevocable trust for my deceased mother using 1041.  She has an annuity earning some income last year so she received a 1099r.  I would like to know how to enter the 1099r information on the 1041 form because I don't know where on the estate turbo tax software. Please help.
