Solved
I keep saying I didn't get a 1099B and checking the box for a sale of a second home. I don't know what to do any more and am very frustrated.
It's called a 1099-B Worksheet, but it's used for all Investment sales in TurboTax. Note that line 2 of the worksheet has a check if you didn't receive a 1099-B.
You don't enter your 1099S directly into TurboTax; you enter the information from it to calculate your gain or loss. The calculation will go to the Form 1099-B Worksheet, then transferred to Schedule D and Form 8949. The "1099-B Worksheet" isn't a form that is filed with your tax return. It's a calculation worksheet for your records.
