How do I update or change my autofill information?

If you mean auto-correct, then there is no way. You can either turn it off and not use it or restore the iPad to a fresh iOS and it will start again. Supposedly, it's supposed to learn how to auto-correct (I believe I've read that somewhere).

However, if you mean to change, delete or add your own shortcuts, then go to Settings > General > Keyboard > Shortcuts and either edit an existing one or make a new shortcut.

Sometimes, I get tired of auto-correct making changes to my typing, so I'll make a shortcut for the phrase that I want. This does prevent the auto correct from kicking in and changing the word away from what I intended.

Hope this helps.

Thanks Mickey but I would like to up at the info for automatically filling out form with my name,address,email etc. The autofill tab pops up on top of the keyboard.
