Can I get the copy of my 2016 tax return? I filed it with Turbotax but it looks like I'm not able to get the copy of it now. Could you advise?

I filed my 2016 tax return with Turbotax and I clicked "Download/print return(PDF)" but it says "It looks like you need to pay first to instantly access your TurboTax returns".  It's just a copy what I filed in 2016.  Why should I pay for it?
