Deployment Section not showing up

I’ve gone through the documentation to set up CircleCI with Heroku, and for the life of me can’t get the deployment part of the build to run. In the build, every time, it says ‘enabling SSH’, and my hunch is that’s the issue. But why/where is it auto enabling SSH?

circle.yml

general:
branches:
only:
- 1262m

deployment:
portal:
branch: master
heroku:
appname: portal-appname

Any ideas why the deployment part of the build just doesn’t run/show up?

Thanjs in advance,
Ryan
