What didn't work? Didn't come out as mono? Is centering of the voice track what you are attempting to do?
Right-click the voice track and SAVE AUDIO AS NEW FILE.
Upload that file to a free server, such as Dropbox, Google Drive, Microsoft OneDrive, etc.
Copy (share) the link to the file and paste it here. We'll take a look. In OneDrive, simply right-click the file and CREATE A SHARABLE LINK. Post that link.
