I'm having the same problem with the same software (2017). My app crashes when I try to open the tax file I previously started because it doesn't have the second state file. When I select the state and click purchase, it crashes. I'm running Catalina (10.15.1).
Regarding your answer, my understanding was that you can't complete a prior year's return on the online version of TurboTax. I thought we had to buy the desktop version. (The user that asked the question is using 2017 and your response is in 2019... So I would think that's not actually an option... Right?)
Additionally, I'm disappointed that your alternate solutions are to try on a Windows machine or just get a refund. I don't have any Windows machines and I don't just want a refund––I HAVE to do my taxes! Why can't your engineers figure this out? I've seen several similar questions on your help forums.
I really need to finish my 2017 taxes ASAP. Please help.
Thank you.
