What you are asking doesn't apply to what you keep stating you need. If you can upload it through Intuit Link, you can do so through DropBox or Box or Sharefile or One Drive or Google Docs or Office Cloud or Adobe Cloud or any other provision that is via the web. And sending by email would be as secure as well, unless they don't monitor their own email address.

Asking if you can upload to someone who wants a fax is like asking if you can email a hamburger to someone who is hungry.
