How to file a 1099-S form, on the sale of my deceased mother's land, on a amended return? The info I have looked up and been sent does not get my to the correct place?

I have looked up and been given info on how to amend, which I have already started, and I was sent info on "where" to file my 1099-S form, but when I pull up, where I was told to go, it doesn't bring up the place to be able to key in my 1099-S form for the sale of land of my deceased mother. I need to know exactly where to go to be able to key that form in on my amended return I am trying to file.
