How do I finish my 2016 taxes on my iPad after the efile deadline has passed ? I can't download the alternative version to my laptop because it's ancient and incompatible

I started my 2016 taxes with Self Employed Turbo Tax . I missed the Efile deadline and was told I had to now transfer everything to the desktop version on a real computer. My computer is Windows 8 ( not compatible with the Turbo Tax download I need ) . I tried to download Windows 10 , but my computer is also incompatible with Windows 10 . How can I just finish my 2016 taxes on the iPad and print them so I can send them in ? Please HELP ! I need to finish these and get it over with . Thank you !
