You said, "If I purchase a past year tax return from TurboTax can I also do the rest of my taxes..."
It's not clear what that means. Do you need to prepare 2016 and 2017 returns, or are you trying to pay to retrieve previously-filed 2016 and 2017 returns that are locked in your online account?
In other words, are you trying to download and print 2016 and 2017 returns that you previously filed but whose access is locked? Or are you asking about purchasing 2016 and 2017 desktop products (downloads) to prepare a 2016 return and a 2017 return?
