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.
(While an amount of $16 won't have much effect on your tax calculation, the economic reality is that you almost certainly incurred out-of-pocket expenses in the course of performing this jury duty (e.g, mileage, parking, meals). For this reason, you would be justified in treating this payment as a reimbursement, not reportable income).
If you choose to report it, go to the Other Reportable Income interview, the very last interview in Wages and Income (Federal Taxes tab > Wages & Income category > Less Common Income subcategory > Miscellaneous Income sub-subcategory). For the Description, enter "Jury Pay".
(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.
