We cannot see your tax return or your account. You do not say what the source of your income was. Did you have a job that gave you a W-2? Or was your $8686 of income from some other source?
You only receive child-related credits like earned income credit, child tax credit or the childcare credit if you had income earned from working. If your income came from something else--like unemployment compensation, Social Security, etc., you are not eligible for any child-related credits. And with less than $9K of income, you have no tax liability unless you were self-employed and owe self-employment tax.
If you did have income from working, then look at your Form 1040 to see what child-related credits you got.

As for it not being "fair" that you do not get a refund....did you file yet? If you choose to use a paid version of the software, you pay to use it no matter whether you get a tax refund or not. With so little income you could have used Free File instead of a paid version of the software. It looks like you are posting from online Deluxe. If you have not filed yet, you could switch to Free File.
If you qualify to use it, there is another full-featured free version of the software:

Note: If you do not qualify to use Free File then you will have to upgrade to Deluxe or higher in the paid versions of the software.
