有難うございます。
以下のコマンドを実行しましたが、同じエラーとなります。
初心者のため、初歩的なところが理解できておりません、どうぞよろしくお願いします
(env) C:\Users\ユーザー\djangogirls\instant-django-master>git add .

(env) C:\Users\ユーザー\djangogirls\instant-django-master>git commit -am "コメ ント"
On branch master
nothing to commit, working tree clean

(env) C:\Users\ユーザー\djangogirls\instant-django-master>git push heroku master

commit時にはコミットメッセージを入力する必要があります
登録エディタが開くので、なにかメッセージ入れて保存登録しましょう

[nikoniko3]

丁寧に有難うございます。
以下のコマンドは、上手くできていないのでしょうか？

(env) C:\Users\ユーザー\djangogirls\instant-django-master>git status
On branch master
nothing to commit, working tree clean

[y_waiwai]

> コミットするものは何もありません。

とおっしゃってますが、
pushは成功してるんでしょうか

[nikoniko3]

何度もすみません、おそらくpushが成功していません。
私の知識では、理解が難しく一からすみません。以下のエラーでした。

(env) C:\Users\ユーザー\djangogirls\instant-django-master>git push heroku testbranch:master
error: src refspec testbranch does not match any
error: failed to push some refs to 'https://git.heroku.com/medipolis-keika.git'
