Turns out External Link Account Exemption can only be submitted by the account owner and if that owner is not associated with the application (added to it) then you can't submit for exemption. As soon as our team added him to the app and then had him be the one to submit we were able to successfully post the form info.
This means even admins on the application cannot submit External Link Account Exemption. Hopefully this helps someone!
