I am having exactly same problem in Turbo tax 2019. Once I entered the information for Dependent child credit, Turbo tax will not allow you to revise the information. There is no way to add new organizations you paid child care, add dependents expenses , change values of expenditures or anything. When you select to update the data in "Deductions" it asks you a couple of questions like if "you earned income as an inmate", then jumps to "congratulate you because you got a tax credit.." and goes back to the Deductions page. It doesn't show you what you have already entered or give you a chance to update any information. This is certainly a bug in Turbotax which I hope will be resolved soon. The other option to delete the forms and to enter the information again is not functional, this is not a solution to the problem!.
