Retirement tax questions

@dmertz 

Following your response that distribution from a trust principal is not reported on Schedule K-1...  I thought the trust needs to inform the IRS who it distributed principal to and how much.  If so, where is it reported if not on Schedule K-1?  By the way, in my process of completing the tax return for the trust and the schedules K-1, I noticed an entry on the K-1 for AMT adjustment.  Does this take care of the distributed principal?

Thanks
