NEVERENDING loop for Mac App Distribution

I have been trying to get an app I invented published and sent to Testflight / sandbox and then after feedback get it authenticated for the Mac OS distrubution store. I am stuck in a circular loop trying to get this to work. I have restarted 5 times now. ANY HELP or can I hire someone to walk me through it
