You may have answered a question incorrectly that resulted in this prompt. Use the tabs to go to the Federal Taxes, Deductions and Credits section, and check "You and Your Family". I recommend going through "Visit All" for that section to make certain all the questions are correctly answered to see whether your problem will go away.
If that doesn't work, you could try the "Walk me through everything" at the beginning of Wages & Income, or "Visit all" in Deductions and Credits sections. There might be relevant questions there that triggered the "demand" for childcare expenses.
