effective tax rate looks wrong

Hoping someone can help!  This is the summary of my taxes.  My questions are 1) if my taxable income is only $17344 isn't my tax really high; and 2) why does my effective tax rate say negative 2.98%? Isn't the calculation tax/taxable income which would be $6273 (or $4878) divided by $17344?  Thank you!
