Entering Prior Year Tax Liability

[dy24]

TurboTax calculated a tax penalty because it doesn't know my prior year tax liability to compare to what was withheld this year.  Where in TurboTax can this be entered?

[MindyB]

Yes. You can enter your prior year tax to be used in figuring the underpayment penalty. Here is how to enter the information in TurboTax Online:

1. Navigate to Federal > Other Tax Situations > Additional Tax Payments > Underpayment Penalties > Start or Revisit
2. Continue through the questions until you are asked to enter the 2023 liability for 2210 purposes.
