How much money will I get back from my tax return?

I am married, filling jointly. I did not work last year. We have 4 beautiful dependents together. He made roughly $3,600 at one job and received a W-2. He then also made roughly $12,000 as a sub-contractor and received a 1099 MISC. We have no weird tax deductions other than the EIC and the Child Tax Credit. Does anyone out there know how much we are going to have to pay in for the 1099 MISC and what our return will look like? Thank you!
