Form 2210 in print format and e-file format will not be available until 2/25/2021 in TurboTax.
TurboTax is currently estimating the penalty for your purposes, but you are unable to file the 2210 and use the actual penalty amount calculated until the print of the form or the e-file of it has been approved by IRS.
If you have a penalty, you are required to submit the 2210 with your return if using the calculated amount of that penalty on your return.
If you wish to file your return now, you would have to let IRS figure the underpayment penalty for you since the form is not yet available to file with your return.
If you wish to wait until the 2210 is available in TurboTax, then you will have to wait until 2/25/2021
after you have updated your software in order to e-file the Form 2210 calculations with the return.
If you are able to wait until the form is released in TurboTax on 2/25/2021, so you can use it to finalize the calculation for your penalty, then you can update your software, complete the calculations and figure it yourself before you file your return.
