Yes, Locky0019 is almost correct, except a little type:
Find your content-end-wrapper.php file in:
wp-content\plugins\dw-question-answer\inc\templates\default
However, I would would follow the instructions on DesignWall’s guide and create the content-end-wrapper.php (or any other template file) in your theme-child and do your modification there; otherwise you will lose your modifications once the plugin is updated.
The styling instructions can be found here:

Once you get your template file ready to go, you have to add:
<?php get_sidebar(); ?>
The code should be strategically added to the correct <div> and adding necessary classes or IDs in order to style correctly. Also make sure that in your WordPress backend you have your widget set to appear on the page Appearance > Widgets …
So, basically, get_sidebar() template funtion will load any widget set in Appearance > Widgets for that page.
Hope it helps someone out there….
