let section = document.getElementsByTagName('section')[0];

if(e.target.tagName=="input"){
section.addEventListener('click', (e) => {
   e.target.style.backgroundColor = 'rgb(255, 255, 0)';
}
});

Your if statement needs to be moved inside the event listener. Also, the result of tagName needs to be capitalized; unless you want to use .toLowerCase() method.

section.addEventListener('click', (e) => {
  if (e.target.tagName == "INPUT")
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
});
