You have to go through the Child Tax Credit section and answer the questions - basically, you need to tell TurboTax that you did not receive any advance payments. Once you click through the screens in that section, the Form 8812 will go away permanently.
To get back to this section to review it, search for Child Tax Credit and use the Jump to Child Tax Credit link to be taken to those questions and go through carefully making sure to indicate that you nor your spouse received any advance payments.
Everyone has to go through that section (or at least confirm what payments, if any, you received as advances) before filing this year - even if you have zero kids and received no advanced payments....
Finally I could delete the schedule 8812 from the forms after going through each step by step child care question. Thank you @DawnC !
"Everyone has to go through that section before filing this year - even if you have zero kids and received no advanced payments...."
Why would I even have to look at this if I don't have dependents? Seems like more of a bug in the program than a helpful exercise.
Just a bug. I received the same error with all 5 tax returns I filled out. I just entered "0". Ran smart check again and the error was gone.
Thank you @DawnC for the response ... but I have to agree with @Thnicedncr it is ridiculous to have to step through all the child related questions if the personal info states that the filer is single, with no dependents. The program (and programmers) ought to be "smart enough" to bypass entire sections related to dependents, children and related payments based on the Personal Information provided/inputted by the filer. I expect to NOT have to answer questions about situations that don't apply - or ask one (1) question that allows a bypass ("does not apply to me") . This is done in other areas and for other topics, why not this one?
