I work from home & will have only made about 4000 when 2017 is over. I have a son that I paid daycare expenses for & I am the head of household. Can I get a refund still?

My son is 3 years old and I paid daycare fees.

I will have made less than 4000 the 2017 year.

I am head of my household. I need the electricity, internet, and home phone in order to work since I work from home. my light bill is $120 a month, and my internet/phone bill is $64 a month, my laptop I need in order to work was $350.

Will I get the EIC, the Child Care credit, and a credit for having a dependent? Even though I didn't make a lot of money will I have to owe the irs? I am not sure how the 1099 form works.
