Why is the filing deadline shown as April 15, 2019 in the printed return, even if I had filed an extension until Oct 15, 2019?

I am concerned that the final print out mentions "postmarked by April 15" as the deadline.

Is this an error in the program? Or did I miss any question while preparing the return, that asked about the extension status?

If you have taxes owed on the 2018 tax return then the taxes had to be paid on or before April 15, 2019 to avoid a failure to pay penalty.  You cannot enter a date after 04/15/19 for the taxes to be paid.  You have to pay the taxes owed when you file the 2018 tax return.

A 2018 tax return can be e-filed using TurboTax up through October 15, 2019.  After that date the 2018 tax return can only be printed and mailed using the 2018 desktop editions as the TurboTax online editions will be shutting down to make way for the 2019 online editions.

I agree on the tax payment deadline, but the print out mentions the return filing deadline "postmarked by" April 15. 2019.

That postmark date is referring to the payment of taxes with the tax return by April 15.  You can ignore that statement.

If you have an extension then the IRS knows it.

Your extension gave you extra time to prepare your 2018 tax return documents.  It did not give you extra time to pay.  If you did not pay your estimated 2018 tax due by April 15, 2019 then when the IRS receives your 2018 return and your payment, they will calculate your penalty/interest and bill you later.  TurboTax will not calculate the penalty or interest.

You have until October 15, 2019 to e-file your 2018 tax return.  After that, e-filing for 2018 will be shutting down, and a 2018 return will have to be printed, signed and mailed instead.  The online software will also be shutting down, so if you are not finished preparing your 2018 return by then, you will have to download desktop software to a full PC or Mac to finish the return.

When you requested your extension you were supposed to pay your estimated tax due.  Did you enter the payment you made into your tax return?  Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes  This will show up on line 17 of your Form 1040
