Need to file robinhood taxes from 2016-2019.

Software for 2016 is no longer available.  And neither is free filing for any of the past years using TurboTax.

Online preparation and e-filing for 2017, 2018 and 2019 is permanently closed.

To file a return for a prior tax year

If you need to prepare a return for 2017, 2018, or 2019 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

https://turbotax.intuit.com/personal-taxes/past-years-products/

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.

There's a small ray of sunshine for you, if all your sales were covered the IRS knows if you owed on a tax return and would have let you know by now if you did.

So if you compute your taxes and you won't owe anything for any of those back years then just keep your records and don't bother filing. Although if you have losses that you could have carried forward to negate the gains that you have this year then it might be worth your while to file the older years. But if you compute the 2020 taxes and you still owe nothing then why bother. This is a judgment call you have to make.
