By yehster:

You need to push to tajemo/openemr.git instead of openemr/openemr (this is the official repository which you don't have permissions for).
using git from the command line it would look something like this
git push git@github.com:tajemo/openemr.git
alternately you can define a remote and then use that
git remote add tajemo tajemo/openemr.git
put push tajemo

You can also redefine "origin" to be tajemo instead of openemr
