How do I file a New York State extension?

[JulieR]

If you already completed (or are mostly finished with) your 2018 state return in TurboTax Online, go back into your state and look for a Need more time to file? or similar extension question or option, usually towards the end of the interview (step through your state again from the beginning if you didn't find it). Then follow the onscreen instructions in TurboTax.

Otherwise, if you haven't (or you just) started your 2018 state return you can use the following alternative instructions: New York (NY) – You can e-file your extension through TurboTax. Start your NY return (if you haven't already done so) and look for the extension question. If you don't see it, step through your NY return again from the beginning. The extension must be filed by April 15 and gives you another 6 months (October 15). If you owe them taxes, submit payment by April 15 to avoid penalties. You can pay when you e-file your extension or pay through their Online Services site.
