I do not have time to finish my return now. Nor do I have money to pay right now. How do I save the file to finish it later?

Simply sign out of your TurboTax account and once you log back in, all of your information will be saved. TurboTax saves your information as you go along. For more information, visit: https://ttlc.intuit.com/community/saving/help/can-i-save-my-return-and-come-back-later/00/25873

YES - You need to file an Extension and send a check with the best estimated amount of taxes owed with it. Then you have 6 months to complete the return.

You do not have to file an extension if you will be able to complete and file your return by midnight (in your time zone) on April 15, 2020.  As AshleyLO mentioned, your return will be waiting for you -- just sign back in!

Otherwise you can file an extension using TurboTax Easy Extension when it becomes available.   If you wish to file your extension before then, you can download the form from the IRS website, complete it, and mail it in.  Click on this link:  Form 4868
