Is  your daughter a full time student?  When will she turn 24?

She is a full time student. She will not turn 24 until 2017.

Thank you.  You are correct. After reading publication 501, I learned that the age of 24 is one of the qualifiers for a dependent child, along with being a full time student. The only issue I would like to point out to TurboTax staff is that a pop-up instruction in the program states the age as 23, not 24.

age of less than 24 is required. 23 is the maximum age of a dependent child.

Under 24 means the same as 23 or younger.

Dependents are always required to file a tax return in their own name for income they earn from working.  For a typical child dependent (under 19 or under 24 and a full time student) this does not prevent you from claiming them as a dependent.

But it kind of sounds like they have never filed before?  They have been required to file in any year their income was more than $6200 (the amount has changed slightly over time).  Not filing means that the IRS creates a substitute tax return in their computer system. which may or may not be accurate.  And the IRS usually won't send a "you forgot to file" letter if a refund is owed, because they don't mind keeping the money. (They will send a "you forgot to file" letter if they think tax is owed.)  If your kids had income over the limit in past years, they should file.
