You do not get back anything that was withheld for Social Security or Medicare. The amount in box 2 of your W-2 is the amount they use to determine how much--if anything--you get back as a federal refund. So if you have an adult dependent for which you are getting the $500 credit for other dependents, and do not qualify for earned income credit then with about $7150 of taxable income, the refund amount you mention sounds correct.
