1098t Amount Billed for Qualified Tution and related Expenses

I paid my tuition out of pocket, was enrolled at least half time and do not have an amount in box 1 "Payments received for qualified tuition and related expenses" but do have an amount in box 2 "Amounts billed for qualified tuition and related expenses." Entering the information into turbo tax, it said i was ineligable to claim my sons tuition. Why am i unable to claim his tuition if I claim him as a dependent and he paid for tuition out of pocket?
    Two possible reasons that the credit might be limited include AGI limitations, and no tax liability to reduce.

    The eligible institution can can choose to report amounts in either box 1 or 2.

    1. When you enter the form in Education Expenses, make sure you enter the form exactly as shown.
    2. Then after the form, TurboTax will ask you to verify how much was paid in 2011. You can enter the true amount here if you have documentation of a different amount than the billed amount.
    3. Also there's a page that asks for any payments that did not get reported on the 1098-t.

    With these three opportunities to clarify the amount paid to the institution, TurboTax will be able to calculate your best refund.

      You could be ineligible if you file married separately or your income exceeds the maximum

        People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

        1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
        2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
        3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
        4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
        5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
