TurboTax software is no longer available for any of those years. And it is too late to receive a refund for any year earlier than 2018. If you owe tax due you still need to pay with penalties and interest.
You could seek local paid professional tax help to prepare returns for those years. Do you have documents to show your income etc. for those past years?
TurboTax software is available for tax years 2018, 2019 and 2020, as well as the current tax year, 2021.
