I sent out a 1099 misc thru turbox in 2017, how do i get a copy of that?

If you used Quick Employer Forms online to create the 1099 last year, you can access through this link and then select the tab for Previous Year at the top of the screen. 

If you used the option in the Desktop version to create the form last year, you would need to open the 2017 software and select you wanted to prepare W-2/1099 to access the forms created and saved on your computer.
