I thought if return started b/4 10/15 you got 'til 10/31 to efile
however, this is from their website

You can e-file your 2019 return all the way up through October 15; e-filed returns in rejected status can be resubmitted through October 20.
After that, e-filing shuts down to get ready for the next tax year, which means you'll have to paper file
