I see you recently cheered the original solution in this thread about preparing a 2017 return. This is a thread that is a couple of years old that transferred into this new Community forum last June.
While it's not too late to file a 2017 return prepared with TurboTax, you cannot prepare the 2017 return in Online TurboTax, (web version) which is only for 2019 returns at this point in time. You would have to use 2017 desktop software as explained in detail elsewhere in this thread.
You may have already known that, but I wanted to make sure you do NOT try to prepare 2017 return using the 2019 Online TurboTax interface (i.e., the web version). We have sometimes seen a user try to prepare the wrong tax year online by mistake.
