Is it too late to file for an Extension

[xmasbaby0]

It was too late to file for an extension after April 15, 2019.    Now you are just late.

Online tax preparation and e-filing for 2018 returns is now permanently closed.  You had until midnight on Tuesday, October 15 to finish and attempt to e-file; if your e-file was rejected you had until October 20 to make corrections and re-file. Now it is too late to use online software or to e-file. If you have any changes/corrections at all to make to your 2018 return, you now have to complete it using desktop software, which you must download to a full PC or Mac  (not to a mobile device).

If you already paid for your online software you can ask customer support for a download of the desktop software.

If you are getting a refund, there is no penalty for filing late.  If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe.  Only the IRS will calculate this—TurboTax will not calculate it.

Yes.  An extension had to be filed on or *before* April 15, 2019 (unless you were out of the country or in the military).   An extension was only an extension to file, not to pay.   Any tax due had to be paid on or before April 15, 2019 of late fees and interest started as of that date until the date paid, extension or not.
