I've noticed array of results when choosing prior year EIC and Additional Child Tax Credit option for repeat and new clients.  I'm not confident the results are correct and have decided to put these clients on hold. 

Sometimes the refund amounts don't recalculate at all when choosing "Prior Year option" and there is a $10,000 difference in Earned Income.

Intuit, please step up and resolve this issue correctly and promptly.  My customers are not happy having to wait and my integrity is on the line here.

Thank you!
