Editing sidebar.php after adding widgets

Hello,

I just finished creating my own theme, during which time I had manually edited and customized the sidebar.php file in the theme folder.

After installing and adding widgets through the admin interface, it seems to now be accessing a different file for the sidebar code as the changes to the sidebar were not made in sidebar.php and any changes I make to this file do not affect sidebar.php

does anyone know if there is a different file being accessed which I can edit?

Ultimately I want to manually add some code to the sidebar.

Thanks in advance to any help!
