Support at Turbotax told me this is a known BUG in Turbotax for everybody with Adoption carry forward credit.
Turbotax will not let you complete the form, just keeps going round in circles at the Review step asking to complete the Adoption for "year adoption was final" but that field is disabled!
Let's get this fixed Intuit please it's been over a week and we are all still unable to file our taxes and carry forward out adoption credits!
