Get your taxes done using TurboTax

once you have input all your info and total AGI is correct you can also trigger the AI process on EasyStep under "Other Tax Situations" and "Underpayment Penalties" will lead you thru the questions to provide the cumulative AGIs for 3/31, 5/31 and 8/31 needed to drive the Form 2210, but likely want to review what is happening in Forms view also.
