No. it no longer supports those years and offers on the internet cannot be updated.
No. TurboTax software only goes back as far as 2019--and 2019 will be gone soon. Even if you could find TurboTax software for those earlier years on eBay, etc., the software is no longer supported and cannot be updated, so you could not get accurate results by using it.
And......any tax refunds for those tax years have been forfeited. Even if your tax forms show a refund for those years, it is too late and the IRS will not pay the refund to you. If you owe tax due though, the IRS still requires you to pay, with penalties and interest.
Why are you asking in 2023 to file 2014 and 2016? Has it been many years since you filed a tax return? Have you had taxable income to enter on a return? Are you way behind in preparing your returns?
Each tax year has to be filed separately using the forms for the specific tax year. They cannot be combined in any way--do not even put them in the same envelope when you mail them. Software for past years is available back to 2019. Any earlier years can only be prepared on paper forms by hand--and those refunds have been forfeited now.
The current online program can only be used for a 2022 return--no other year. And if you did not file a 2021 return you will have trouble e-filing 2022. When it asks for your 2021 AGI try using zero. If zero does not work then you have to print, sign and mail 2022
TurboTax has software for 2019 onward. Software is no longer available from TurboTax for earlier years, nor would it be supported even if you find it on eBay, etc. Updates are not available. It is also too late to receive a tax refund for a tax year earlier than 2019---those refunds have been forfeited. BUT if you owe tax due you still have to pay with penalties and interest. There might be other software providers that have software for those years, but you will not receive refunds for the returns even if the forms show a refund.
It might be better for you to seek local paid tax help in a situation when you are several years behind in filing your tax returns. Do you even have all of the documents you will need to enter and show your income—like your W-2’s and any 1099’s?
Online preparation and e-filing for 2019 and 2020 and 2021 is permanently closed.

You may also want to explore purchasing the software from various retailers such as Amazon, Costco, Best Buy, Walmart, Sam’s, etc.
Remember to prepare your state return as well—if you live in a state that has a state income tax.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
