The 2210 will not be available for paper filing and e-filing until 2/25/2021 in TurboTax.
The 2210 is a estimate until the final form and e-file approval has been received from IRS and cannot be used without the Form 2210 in the return.
Therefore, if you want to file your return before that, then you will have to let IRS calculate the penalty for you since Form 2210 will not be available to be used until after 2/25/2021.
If you are able to wait until the form is released in TurboTax on 2/25/2021, you can use it to calculate your own penalty, then you can update your software, complete the calculations and figure it yourself before you file your return.
