Why is the child care credit saying we don't have any earned income, even thought I already entered it?

[Carl]

I assume this is a joint tax return being filed with a filing status of Married Filing Joint.

 - Did both tax filers work *and* have taxable W-2 income in 2016?
 - Was either tax filer self-employed, and after all the business deductions, there was no taxable business income maybe?
 - If each tax filer received a W-2, did you correctly identify who each individual W-2 (or 1099-MISC if you got that) belonged too?

On a joint return, both tax filers are required to have "taxable" income, in order to qualify for the credit.

The only exception to the above, is if one tax filer was either 100% disabled for the entire year, or was a full time college student.
