How do I add the amount from line 11 of form 1040 onto line 7 of form 2441 if I have not finished the rest of my return to generate form 1040?

I have never had to complete this form before and have done nothing differently this year.  I have been asked to complete form 2441 and t asks for the amount from line 11 of form 1040.  Am I right in thinking that form 1040 is the completed return?  If so, how do I get info from the completed return if it hasn't been generated by TurboTax yet?
