Times New Roman Font Issue?

I have a problem with my quotation marks. A large portion of my quotation marks are straight, like this: ", but then others look like the typical, curlier quotation mark. Apparently, they're in the same set, both Times New Roman, but look different, and it's bugging me. I want all to look like the curlier quotation mark, but I can't do it. When I try and select and replace in the auto-replacer, it can tell no difference between the two types. The only way I can do it now is by manually deleting the straight looking quotes and typing in the curlier one (the curly one types naturally when I type a quote, fortunately). I actually don't even know how to reproduce this straight quote. Any solution is an easy 10 points, although a solution might be hard to come by, I know... Thanks for the help, regardless.

I am running Mac's Microsoft Word, the newest version with the latest update. However, I don't think that's the problem. If it is, all the better if there's a solution.
