Now that my submission has been accepted, how do I edit to correct my title spelling? I am not seeing any choices to edit on my contributions page. Please help.
Welcome to the forum 
You cannot edit from your contributions page once a wayspot has been accepted, as it is not “your” wayspot. To edit an existing wayspot, regardless of who submitted it, you need to get close to it, then open it in Pokemon Go and got to the page for suggesting edits and adding photos.
