that portfolio income on the 1041 should also be on the grantor trust letter. What you are reporting is not typical of grantor trust reporting. A grantor trust will have wording on the 1st page that it is a grantor trust and will have no income or expense reported on page 1. all income and expenses would be reported in the grantor trust letter. However, I can offer no assurances the the interest income reported on page 1 of the 1041 is also included the grantor trust letter.
these are IRS instructions
If the entire trust is a grantor trust, you’ll need to fill in only the entity information on Form 1041. Avoid showing any dollar amounts directly on the form itself; instead, include dollar amounts only on an attachment to the form. Additionally, do not use Schedule K-1 (Form 1041) as the attachment.
