I need the pdf version of my 2018 return but I used the free version. As a result how can I get the pdf now after filing?

How do I get a copy after filing on free online version

I just filed mine and do not have the option to download. I only have an option to ReFile and View.  And when I view, it just takes me to the completed Federal return page. Can I pay after it has already been submitted via Netfile so I can print a PDF version?

In TurboTax2018 goto View -> File and you should see the PDF version here. I don't know why they don't do this from the main menu.
