How to report errors in TurboTax Deluxe Desktop form for Delaware Tax return

jh73 — Sun, 22 Feb 2026 20:19:24 GMT

I have been unsuccessful in finding out how to report bugs in TurboTax for the 2025 Delaware state return. When the program ran a check for the state return, it displayed the following:

Check This Entry

Form PIT-UND: Prior Year Tax from last year’s Delaware Form PIT-RES line 12, or …."

In addition, the Underpayment Smart Worksheet for Form PIT-UND, Underpayment of Estimated Taxes, for item c states "Enter 2024 Delaware Tax from Form PIT-RES, Line 32 minus 33, or …."

Both of those items are incorrect. Line 12 of the last year’s tax return form is Delaware Adjusted Gross Income, not prior year tax. Line 32 is Total Non-Refundable Credits. Line 33 is Balance. The 2025 Delaware Form PIT-UND states to use “Line 33 Form PIT-RES minus Line 34 Form PIT-RES, or Line 48 Form PIT-NON".

It's not a matter of not getting deductions. TurboTax is not correctly implementing the calculations for Form PIT-UND. The instructions disagree with Delaware instructions for filling out the form.

Thanks for the suggestions, but they do not resolve the issue.

As of 2026-03-26, the TurboTax PIT-UND form for Delaware still contains incorrect information. According to the official Delaware 2025 Form PIT-UND, the correct calculation uses "2024 Delaware tax liability (Line 33 PIT-RES minus Line 34 PIT-RES, or Line 48 PIT-NON)".

Clarification: The Underpayment Smart Worksheet contains the error.

Since you are using the Desktop version, go to the Forms Mode.

Open your return and click the Forms icon (top right).
In the list on the left, find the DE PIT-UND and the Underpayment Smart Worksheet.
Look for the field calculating the 2024 liability.
Override: Right-click the field and select Data Override (or press Ctrl+D). The field will turn red.
Manually enter the correct liability from your 2024 return.

Once your state return is finished, you will need to print and mail your return.

It's not necessary to override anything. And besides there used to be consequences to doing an override: if I recall correctly, TurboTax would not then guarantee the 100% accuracy of your tax return.

No override is needed. Just provide the correct calculation in the Underpayment Smart Worksheet, item c states "Enter 2024 Delaware Tax from Form PIT-RES, Line 32 minus 33, or Form PIT-NON, Line 48 ...." Just provide the amount based on the true Delaware form: "Enter 2024 Delaware Tax from Form PIT-RES, Line 33 minus 34, or Form PIT-NON, Line 48 ...."
