You just prepare and file your tax return normally. The extension did NOT give you extra time to pay your tax due, so if you owe when your return is ready to file, pay what it says you owe when you file, and then expect a bill from the IRS later--for the extra penalty and interest they will calculate. TurboTax will not calculate that. If you are getting a refund, no problem at all. There is no penalty for filing late if you are getting a refund, and you did not even need an extension if you are getting a refund.
You have untilOctober 15, 2019 to e-file your 2018 return. If you miss that deadline, you have to print, sign and mail it.
