bug underpayment calculation

The federal carryover worksheet correctly shows the tax liability for 2023. However, the amount entered on Form 2210, part 1, line 8 shows a higher number. This discrepancy causes a penalty to be calculated when it should be zero.

Thank you for sending your token.

 

When your income is over $150,000, your safe harbor for estimated payments is 110% of your prior-year liability. Line 8 of Part I of Form 2210 is 110% of your 2023 tax liability. You would have needed to pay the lesser of this number or 90% of your current year liability to avoid the underpayment penalty.

Is there a reason I have not received a response to my question after having sent my token number?
