Phone call. Reply with text missing

[Tj13]

When I get a call and the phone is locked the reply with text option is missing, only remind me later. If the phone is unlocked it's there.
What setting am I missing?
iPhone 6. 8.02 vzw

I think you have to set it up in settings (go to phone settings and enter some automatic replies)

I finally found it under the Touch ID settings
