My dad died in 2017 in the USA, and my brother and I inherited. His house was owned outright, and not sold until mid-2018. We each received a 1099-S showing our share of the proceeds based solely on the selling price.
His estate was well under the threshold for federal estate tax and he lived in a state with no state inheritance tax. My brother was the executor, and the accountant who had done my father's federal and state returns for years prepared the final returns for 2017.
My brother (US person) and I (dual national) paid no US tax on the proceeds of the sale. In addition to other forms that I always file, my 2018 return included a Schedule D and Form 8949. The adjustments on the Form 8949 included RE commission, and other costs associated with the sale. We actually had a paper "loss" as the house sold for slightly less than its tax value, which was the relevant value for our "basis".
Generally you won't pay any tax on the sale of inherited property unless you get lucky and make a substantial gain. Hope this helps.
