Hi Hus123,
Just give them from 18 like they asked.
They just want it updated to see if you currently moved or your address changed.
How you can add the info under your profile is:
Click on PROFILE which is on top right hand corner.
This should bring you to your profile and you should see FORUM PROFILE INFORMATION on the fas left side.
Click on it and then you have your page with information you can fill in and make sure to save changes.
