After you file

Yes.  E-filing for 2018 will be open until October 15, 2019.  After that a 2018 return has to be filed in the mail.  if you are getting a tax refund there is no penalty for filing after the April 15 deadline; if you owe tax due then you need to file and pay as soon as possible, since penalty/interest began to add up after April 15.
