The IRS should not need the Form 2210 to be sent with the return unless you are requesting a waiver of the penalty, and this could be why you don't see the form in the package of forms.
If you want to force TurboTax to print the form by requesting a waiver, in TurboTax Online:
- Open your tax return.
- Select Federal, then Other Tax Situations.
- Select Start or Update to the right of Underpayment penalties.
- You can trigger the waiver by answering Yes to Penalty Waivers.
- This will remove the penalty from your return, but it should also print the Form 2210.
- If you don't want to request a waiver, you can go back through the interview and change your choice.
