I need to file for years 2021,2018 and 2017 can I use the online system and then paper file?

The TurboTax online editions are only for tax year 2022.

TurboTax only supports tax years 2022 thru 2019.

Any prior year tax return before 2019 being filed with a tax refund will not get the refund paid as it is after the 3 year limitation from the due date of the tax return.

If taxes are owed for prior years the payment should be made as soon as possible since penalties and interest will continue to accrue until the taxes are paid.

You should seek out a local tax professional to assist you in filing these prior year tax returns.

For tax year 2021 you can purchase, download and install on a personal computer one of the 2021 desktop editions from this TurboTax website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2021 tax return can only be printed and mailed, it cannot be e-filed using TurboTax.

No.   Sorry--The online software is only for 2022----no other year.

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.

To file a return for a prior tax year

 If you need to prepare a return for 2019, 2020 or 2021 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

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.

Note:  The desktop software you need to prepare the prior year return must be installed/downloaded to a full PC or Mac.  It cannot be used on a mobile device.

If you are getting a refund, there is not a penalty for filing past the deadline.  If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.

You only have until April 18, 2023 to file a 2019 return and still receive a refund.  If you file a 2019 return past that deadline, your 2019 refund will not be paid to you—it will be forfeited—the IRS will keep it.
