I would like to file form 2210, underpayment tax waiver. Where do I do that on turbotax?

[ChristieB]

You can request a waiver of underpayment of estimated tax by taking the following steps in TurboTax: 

1.) Federal

2.) Other Tax Situations

3.) Additional Tax Situations - Underpayment Penalties

This section will help you determine if you qualify for a waiver, and also update your Form 2210 with this information.
