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".
