Thank you for giving me the opportunity to assist you. I will give the best answer that I can with the information provided.
If you don't itemize (probably not if you don't have a house or a lot of employee business expenses) then you will need to use Form 1040A.
If you qualify as head of household, and your child is under 17 years of age, your estimated refund would be $1902.
Please let me know if you need more information.
