How to file 2015 Taxes with Turbotax

[kevinbaker2275]

This my first time using Turbotax. I am filing back taxes for 2015 to 2018.  Since Turbotax no longer supports online filing for 2015, I have purchased a desktop version. My question is how do I actually file my 2015 taxes? Does the IRS even allow online filing of the 2015 taxes? If not, would I print and mail my 2015 tax returns. Comments and suggestions appreciated.

You cannot efile any tax returns other than 2019 using TurboTax. All prior year returns must be printed and mailed. TurboTax only provides prior year tax preparation programs for the 3 years prior to the current year so 2015 is not available from TurboTax any more. 

You have 3 years from the tax returns original filing deadline to file a return for a refund. You should still file older returns if you have not previously filed them but they are not eligible for a refund. You must, however, pay any taxes due on a prior year tax return regardless of how old the tax return is.
