You can no longer file for an extension as the deadline date was July 15.
See this TurboTax support FAQ for checking the status of an e-filed tax return - https://ttlc.intuit.com/community/return-status/help/how-do-i-check-my-e-file-status/01/25538
If the status is anything other than Accepted, the tax return was not e-filed. You can still e-file a 2019 tax return using TurboTax up through October 15, 2020.
If you have not paid for the TurboTax account or the federal tax return was not Accepted by the IRS, you will not be able to view or print your complete tax return.
