"Schedule K-1 form 1041 does not show address for the trust."
The IRS already has the correct address for the trust, as well as for the beneficiary(ies), from the 1041 and K-1(s) that were filed by, or on behalf of, the trustee.
Thus, you can use any address (including your own address) since the copy of the K-1 you have is for your records only and, other than the figures and the trust's name/EIN that you input from the K-1, does not get filed with your individual return.
