Prepared client's 2021 return.  Form 8812 did not allow refundable child tax credit because Earned Income Worksheet Part IV line 23 did not include her self-employed wages (because they were exempt from SE tax). 

Client received CP12 indicating 8812 computation of credit was incorrect and client's return is being adjusted and the RCTC is being sent.

So it appears as long as she has earned income she is eligible for the credit.

Proseries please look into this. 

I can provide tax notice (with client's permission), if needed.
