If AutoFill won’t work
Safari can automatically fill in forms, user names, and passwords for you. If this feature isn’t working, here are some things to try.

Make sure AutoFill is turned on

Open Safari if it is not already open.
Open Safari
Choose Safari > Preferences, and then click AutoFill.
Select “Using info from my Address Book card” and “Other forms.”

>>>“Using info from my Address Book card” and “Other forms.”>>>>

Everything is checked that can be checked but the above doesn't appear on screen as an option.

Edit: I see "other forms" .... but no "address book."

If you don't put your address and phone on your card in the address book, it won't autofill.

You should be able to find it in your launch bar, usually at the bottom of the page, unless you have specified that it be at one side or the other.

If you can't find it there do a search and it should pop up in your applications folder.
