No. After October 15 you have to print your tax return, sign it, and file it by mail.

No Efiling is closed now.  You have to print and mail it now.

You now have to print and mail 2018.  Be sure to attach copies of your W2s and any 1099s that have withholding on them.  You have to mail federal and state in separate envelopes because they go to different places.  Get a tracking number from the post office when you mail them for proof of filing.
