Why is my refund $2000 less when nothing changed on my end?I am a single, sahm, not head of house, but have a small business, and claim both my daughters. Please help!

I have zero child tax credit showing up, I’m so mad! This is typically my income for the year and makes it so I can have my business please help me figure this out, it’s soul crushing. 
I filed the same earned income last year?
