Still need to file your 2015 taxes?
Although TurboTax Online 2015 has shut down, you can still file your return using the TurboTax CD/Download software.
Simply order the software, install it, and prepare your 2015 tax return as usual. You'll need to file a conventional paper return, as e-filing 2015 returns is no longer available in TurboTax.
If you're expecting a refund, you have until April 15, 2019 to paper-file your 2015 return and claim your tax refund.
