Creating a child theme

I have been tasked to create a child theme, because I am not free to alter the parent theme.

I created a new style.css for the child, and put it into the child themes folder. This is how it is declared:

/*
Theme Name: My Child (Child von Parent)
Theme URI:
Description:
Author: myself
Author URI:
Template: ParenT
*/

@import url("../ParenT/style.css");

Now, when I look at the new theme in Dashboard, it gives me the following text:

… the templates are in /themes/Parent/someSubDirectory …..[my translation from the German text]

So, let’s say, I wanted to replace home.php of the parent theme with a similarly named home.php that I put into the child theme’s folder. But since the template is not properly referenced, WordPress is looking in the wrong place, to see if this is a new file or a replacement.

I hope I could explain this in an understandable manner. My question: how do I achieve it, that the reference points to the correct directory in the parent theme.
