Can you email me a copy of my 2016 return? I did not use turbo last year and don't need it this year and beyond.

No.  Your return cannot be emailed to you.   No one else has access to your account or your tax returns.  You have to obtain it yourself by accessing your account and then print it out for yourself.

You can get a free transcript from the IRS:
