Deductions & credits

Line E is the line for the child tax credit it is asking me to input the value that applies to me “4” for each dependant  if im single and make under 71k. “1” for each dependant  if i make over 71k and “0” for each dependant if i make over 200k . Seeing that this tax credit doesnt apply to me i have no children dependants what value should i put on this line?
