Sold after death = reportable by owner as of time of sale, i.e. trust

Since when does the trust document have anything to do with the tax law?  But the remainder owners get stepped-up basis on the full value of the house, so where is the gain?  Was it not sold right away?

These arrangements are done by people who want the taxpayers to cover the cost of the nursing home so the estate can cover the cost of the beneficiaries' cruise.  

I stated the facts incorrectly. Trust was created in 2018 and the deed was changed to the trust. The house was sold in 2019 when the grantor entered care facility. Grantor passed in 2020. The taxpayer has told me that the attorney who created the trust document intended for the grantor to report the house sale using the exclusion of gain rules. I cannot find documentation to tell me where to report the sale - the trust return or the individual - or both.

Please see my updated post and thank you for taking the time to reply.

What makes you think the trust was irrevocable?  If this were a typical grantor trust, the sale would go on the individual's 1040 and the Section 121 exclusion would apply.  But the result might be different, depending on the terms of an irrevocable trust.  And have you seen the deed?  It could have reserved a life estate for the owner -- who then would have to have been paid for it, since she was still alive at time of sale.
