Since you only received a check (not a Form 1099-MISC), you can enter the amount as Other Reportable Income.
This avoids the need to use either the 1099-MISC interview or the Business Income features of higher versions of TurboTax.
Go to the Other Reportable Income interview, very last interview in Income and Expenses (Federal > Income and Expenses > Less Common Income > Miscellaneous Income ). For the Description, enter "Settlement".
(Or enter "other reportable income" in the Search Box and select "jump to other reportable income". These payments are NOT wages).
This income will appear on Line 8, Form 1040.
