Sorry---software for those years is no longer available from TurboTax. TurboTax has software for tax years 2021 up to the current tax year 2024. It is too late to get refunds for 2017, 2018 or 2019; if you owe tax due it is still owed with late filing penalties and interest.
There might be other software companies still offering software for those years or you can seek local paid tax help. Past year returns cannot be e-filed. They must be filed by mail, each year mailed separately.
