You can also change to e-filing from mailing. See this TurboTax support FAQ for changing from mail to e-file - https://ttlc.intuit.com/community/e-file/help/how-do-i-change-from-mail-to-e-file-in-turbotax-online...
There are no penalties for filing after the due date if there are no taxes owed or there is a tax refund.
