Trust taxes on IRA, Life Insurance, Annuities

My father has passed this past year and I'm now the successor of the trust.  We had not distributed any of the funds from several IRAs, Life Insurance, and Annuities that have listed the trust as the beneficiary and been deposited into the trust account.  Can I distribute the funds and then do the 1041 with K-1's for the others siblings and show they need to pay the taxes so we don't have to pay 37% taxes on these funds or not.
