Hi,

This theme has 6 main positions for widgets area.

1/ Main sidebar - near the main content.

2/ Sidebar on the footer widgets area: Footer Column #1, Footer Column #2, Footer Column #3, Footer Column #4 ( based the settings via Customize > Footer Options )

3/ Sidebar for header sign-up form below the main navigation

4/ Sidebar for Footer Signup Form - below the footer widget area

5/ Sidebar for Top Instagram - Display instagram at the top

6/ Sidebar for Footer Instagram - Display instagram at the bottom.

All other sidebar can be custom sidebar for Main Sidebar.

I think you can give it a try for each sidebar to know where it displayed

Best Regards,
