Did you get a 1099G or 1099MISC? If no I wouldn't claim it at all.
If you really want to just add it to the Other income Line on the 1040. And on the dotted line, immediately before entering the total pay, write “Jury Duty.”
IF jury duty pay is money that you received to compensate you for time spent on a jury, it is considered taxable income. The IRS requires you to report this type of income on a Form 1040 (Line 21). The Form 1040-EZ does not have a place to report jury duty pay (Other Income, not subject to employment taxes). In this case, you will have to upgrade to TurboTax Deluxe to prepare a return with jury duty pay. Jury duty pay is entered in the Jury Duty interview, under Federal Taxes > Wages and Income > Less Common Income.
IF, however, jury duty "pay" is intended as reimbursement for casual expenses you incur as a consequence of jury duty (e.g. travel, parking, meals, child-care), it would not be considered "compensation" for your time and not reportable as "income".
