Thanks for your reply. 

I am supposed to report the sales price as the proceeds on Form 8949(d). The sales price was $200,000. There were closing costs of $18,000, so the check the executor received was for $182,000. Basis is $182,000. 

I'm asking whether I can put in an $18,000 adjustment for the closing costs on 8949(g) to bring the gain to $0. Or if I can, alternatively, report $18,000 of deductions for closing costs more generally. Or is the estate stuck reporting $18,000 of gain because the expenses of sale cannot be used at all on the 1041?
