Sorry, but it's no longer possible to e-file a 2020 tax return with TurboTax.
Right now the IRS (not TurboTax) has shut down all e-filing of personal tax returns until filing for 2021 begins, probably sometime in late January. No one can e-file any tax return until then.
When the IRS reopens e-filing in January, tax professionals using professional software will be able to e-file 2020 tax returns as well as 2021. But TurboTax does not allow e-filing of past year returns. If you find a tax professional who uses ProSeries software, they should be able to open your TurboTax tax return and e-file it for you.
