Create Redirect Page

I am trying to auto redirect from a different URL on my site to a new one. We recently changed our website navigation and now our QR codes on our business cards that link to .com/about-us/learn-more don’t work. I tried to manually make our new About Us page this exact URL but it will only allow me to do .com/about-us-learn-more which won’t work. How can I create a redirect so if someone uses the old QR code they can visit the new page ending in .com/about-us?

Thanks in advance.
