It sounds like the "Saver's Credit" which would be on your W-2.
If you contributed through your paycheck and you don't want to pay for the TurboTax upgrade required, go to the Personal Info section and tell the program you are a student.
This will not affect your tax return (except that you won't get that $5 credit) but it will trick the program to not upgrade for the reason of the savor's credit.
Students can take the Saver's Credit.
