Print a copy to pdf and either send via Link, password protect and send via e-mail or use a secure drop box for pickup. 

Or print a paper copy for the client, if that is what they prefer.

I do one of two things 

• Paper copy about 80% (I and most of my clients are old fashioned.) Delivered before filing return, some picked up and some by US mail as whichever works best for the client.
• Email password protected copy direct from Pro Series for all those for whom that works, the other 20%
