Are you claiming the Disability Tax Credit for this person? The medical expenses may not be utilized to bring taxes owed to zero because the disability tax credit applied has already brought taxes owing to zero. As we cannot see the previous entries that may affect this credit, we believe your best option is to contact our telephone support team for further assistance, as they have the option to view your screen to help resolve the issue. To contact them, please follow this link: Contact Us. When asked if you wish to receive an email say NO then say "speak to a representative" then hold the line.
Thank you for choosing TurboTax.
