I found the problem! I evidently entered a zero when asked about “2024 state estimated taxes paid in 2025;” we had none. After removing the zero, no more error codes! I discovered the TurboTax Support solution following below.
Thank you to everyone who posted helpful tips!
How to Correct the Error in TurboTax
Navigate to Estimates: Go to Federal Taxes (or Personal > Income & Expenses) > Deductions & Credits.
Locate Estimates: Scroll down to Estimates and Other Taxes Paid and click Start or Revisit next to State Estimated Taxes for 2025.
Edit the Payment: Select the Colorado payment you made and edit the details.
Change the Date: Ensure the date for the 4th Quarter payment is set to a 2025 date (e.g., Dec 31, 2025) if you want it to appear as a 2025 payment, or ensure it is correctly categorized as a 4th quarter payment if it was paid on January 15, 2026, to ensure it doesn't inflate earlier quarters.
