Is it to late to file for a tax extension?

[xmasbaby0]

Yes, unless you are out of the country it is too late.  You had to request an extension by April 15, 2019.  Now your tax return is just late.  If you are getting a refund, there is no penalty for filing after the deadline.  If you owe tax due then your penalty/interest began to add up after the deadline on April 15.  Get your return prepared and filed as soon as possible, and expect a bill for the late penalty/interest.  TurboTax will not calculate that.

You can efile your return until Oct 15.  After that you have to print and mail it.
