The parentheses are used to indicate the parts of an in-text citation not included in prose. Also notice that the parts of the parenthetical citation (author, year, page) are separated with commas. Lastly, notice that the "p." is used for a citation on one page and "pp." is used for a citation that spans multiple pages.
The punctuation in your own writing follows the parenthetical citation. This is the case even when the citation is for a block quote (a long, indented quote, not surrounded by quotation marks).
