Probably, but it will depend. If you have an income of less than 20K, and you are filing head of household your standard deduction is $9,350. You will be receiving an exemption for both you and your 16-year-old of $8,100. With that alone you have a subtraction from your taxable income of $17,450.
Depending on how much more income you have over that $17,450 another dependent on your return will eliminate your taxable income. So assuming you claim all of your kids you are eligible to claim, you would have $0 taxable income so you will receive a refund of everything you paid in.
Now since your 2 older kids are in college, you may qualify for the refundable portion of the American Opportunity Tax Credit AOTC. This could increase your refund. So, you will likely receive a larger refund by claiming your college-age dependents.
