Can I e-file my 2019 amended return with TurboTax Online?

According to https://turbotax.intuit.com/tax-tips/amend-return/how-to-file-an-amended-return-with-the-irs/L6kO691...
Beginning with the 2019 tax year, you can e-file amended tax returns.

It says here that it works for 2020: https://ttlc.intuit.com/community/amending/help/how-do-i-amend-my-turbotax-online-return/00/27577

I do not see any option to do so in TurboTax Online for 2019.
