Hear from a supervisor? Apparently, you're under the impression that I work for TurboTax. This is a public user-to-user forum and I'm just another user same as you. But I don't see a bug. I only see user error.
If you enter a value of 0 for the cost basis of the land, then you're telling the program you don't own any land. So if you then provide a sale price for land, as far as the program is concerned, you sold land you never owned. From the program's perspective it can only be a short term gain. Since the IRS says you have to have a value for the land, you can't have a land value of zero. While there are some exceptions to that, I can figure you don't qualify for such an exception since you didn't state you never owned or inherited land.
If you purchased the property, then a portion of what you paid was for land. If you inherited the property, then the value of the land was the FMV on the date the person you inherited it from, passed away.
I'm wondering if what you're calling the "structure" price included the land, or if the provider of that information you have, just forgot or for whatever reason didn't include the value of the land.
On the old HUD-1 closing statements there was no separation of land/structure values. One always had to refer to the property tax bill in order to figure the ratio of land to structure value, and then apply that ratio to the actual price paid. From what I've seen of the so-called "new and better" closing statements, they're about as helpful with this stuff as matches are in a gasoline refinery.
