You would have to download a pdf copy of your return and give him the pdf or a printout.
If your CPA uses one of the professional Intuit programs you can probably give him the file ending in .tax2016 so he can open it in his program. I would download the pdf or .tax2016 file and copy it to a flash drive to give to him. Do not email it. It is not safe to email highly personal information.
