My first comment is to back up a bit and ask if it should even be on the 1041.  Many home are owned as Joint Tenants with Rights of Survivorship (JTWROS), in which case the living spouse would own the entire home after the death of the spouse (and therefore the entire sale would be reported on the 1040 of the surviving spouse, and nothing on a 1041).

What circumstances are there that the sale is being reported on the 1041?  Is the entire sale being reported on the 1041, or only half?
