On the beneficiaries k1 input page just above where you input the percentages, did you enter the amount of distributions for each beneficiary on line A-2?

I think that is how I did it and it carried to page 2 line 10 of the 1041.

(4 hours later) I just remembered - Also on the schedule D input scroll all the way down to part III,

there on line 18a you can input how much of the capital gain to allocate to beneficiaries, rather than the trust. Took me a while to find that part when I got hung up on it a couple of weeks ago.

Hopefully the above gets you where you are trying to go.
