For a federal 1041 for an estate, do I need to file K-1 with the 1041 and do I need to use each individuals social security number?

I am the executor for an estate and trying to get ready to file the first and final 1041. The taxes on the income from the estate will be paid by the estate. Not sure if I have to produce K-1 with each beneficiary's distribution since it should not be taxable to them.
