This refund amount is possible. If you have input all the data correctly, it may also be accurate. To get a better idea of any potential problems I would start by comparing this years return to last years return looking for any significant differences. Once you have identified any areas of concern you will be able to correct any input errors or at least return to me with comparative numbers. The more detail you provide me the better able I will be to guide you.
