need an extension

Use this for an extension: https://turbotax.intuit.com/irs-tax-extensions/

An extension only extends the deadline to file a return. You must still pay an estimate of taxes owed by today, July 15. 

If you are getting a refund, you don't need an extension because they are no penalties for filing a return with a refund after the filing deadline.

The short answer is you can file an extension through TurboTax or through the IRS.

Longer answer is we have a whole bunch of resources and options for extensions;

Keep in mind: An extension doesn't give you extra time to pay your taxes — but it will keep you from getting a late filing penalty. (You'll still owe interest if you pay after the deadline). But the IRS does offer payment plans if you qualify;
