You cannot get another extension for your 2019 return. An extension request for a 2019 return had to be filed by July 15, 2020, and the deadline to file that tax return was on October 15. If you tried to e-file it by October 15 and it was rejected you have some extra time to fix it and try to e-file it again. There are no second extensions.
But your return is late. If you are getting a refund or do not owe, then there is no penalty for missing the October 15 deadline. If you have tax due, then you are subject to interest and penalties for missing the deadline.
If you have not yet started your 2019 return, you are too late to use the online program. Online is closed for new returns. If you need to start a new 2019 return you need the downloaded desktop software on a full PC or Mac.
