The body of your paper should have a first line indent of half an inch. Instead of using the tab key, use the Paragraph option in Word to set it up automatically. Right click on the page, select Paragraph then go to Indentation, from the drop down menu for Special: choose First Line. See below:
Your list of citations at the end of your paper requires special indentation called a Hanging Indent. After the first line, all subsequent lines should be indented half an inch. Before you start typing your citations (after your page title), right click and select Paragraph, then from the Indentation part of the dialog box, choose Hanging from the drop down menu. (See below)
If you already typed your citations, click and drag to highlight them then press CTRL+T on the keyboard.
An alternate way to do it is to highlight, right-click and choose Paragraph.
Then choose the Special: Hanging indent.
