I'm not sure what you mean by the "whole process," but if you are going to file an extension you need to do it today (Monday) before midnight in your time zone. You will need to estimate what your tax bill will be for 2018. [It doesn't have to be exact.]
To file an extension, please follow these steps:
TurboTax Online
- In
your return, type extension in the Search box at the top of the
page.
- Click
the Jump to extension link
- On
the Need More Time to File Your Return? screen, click on the blue
box, Start Easy Extension.
- Click
Continue in the pop-up window.
- On
the next screen click the File an Extension box.
- Continue
through the screens, entering the requested information.
TurboTax CD/Download
You cannot e-file an extension from the TurboTax CD/Download
editions. You can print out Form 4868 and mail it in. To do this
- Click
Federal Taxes > Other Tax Situations
- Under
Other Tax Forms, click the Start/Update box next to File an
Extension.
- On the
next screen, mark the Yes radio button and click Continue.
- Continue
through the screens until you reach the screen, Your Extension Results.
Click the Print Extension box.
You can also go to the TurboTax Easy Extension website to file your
extension online:
- Go
to: https://turbotax.intuit.com/irs-tax-extensions/
- Click the File
a Free Extension box.
You will be asked to sign in with your TurboTax Online ID. If you
don't have one, click Create an Account at the bottom of the sign in
screen.
