The way I see it, you are looking at maximum taxable income of about $2,000 which should be taxed at the beneficiary level.
You mentioned 10,000 of property sold. As Bulldog mentioned it is safe to say that will be offset by stepped up basis. Report it on Schedule D of the 1041 and call it an unknow asset of decedent.
As I understand your post, that leaves $2,000 of potential income to report on the 1041. That will go on K-1 if reported on final 1041 or distributed within 65 days of estate year end. The result should be in $200 - $400 of federal income tax to beni’s,+ whatever your state might tax.
If these are the only items reported on 1041, they will offset by any legal and accounting fees….etc; in full proportion.
So before you spend to much time digging into this, you should consider the cost vs benefit to the estate and discuss that with them.
