In my review it says I need to fix the dates for the length of time I lived in TN. The dates I am using are from 1/01/2025 to 12/31/2025. How do I fix this?

The response I keep getting is, the dates entered result in more than 365 days.

where are you entering this because TN does not have a personal income tax? All you should need to do is answer that you lived there all year

If you are a resident of Tennessee for the all of 2025, in the My Info section of the program you should have indicated that your Resident state was Tennessee.  If you did not live in another state in 2025 or make money in another state in 2025 then you should have answered NO to those questions in the My Info section.

When you a resident of a state for the entire year, the program will not ask you for your residency dates. 

Since you are resident of Tennessee leave boxes 15, 16 and 17 blank (empty) on the TurboTax W-2 or on the TurboTax Form 1099-R boxes 14,15 and 16.

The program's internal "math engine" is likely counting both the start and end dates as full units (or sees 1/01 and 12/31 as overlapping with a previous year).

The easiest way to clear this "error" without changing your tax liability is to shift one date by 24 hours (Change the dates to: 1/02/2025 to 12/31/2025 or 1/01/2025 to 12/30/2025).

Tennessee has no state income tax, so shifting your residency by a single day will have zero impact on your state tax return.  

You should also check your "Personal Info" section for the question: "Did you live in another state in 2025?"  If you lived in TN for the whole year, make sure this is marked "NO."  If it’s marked "Yes," the program generates a "Part-Year Resident" worksheet that demands dates.

Note: the only reason TurboTax cares about these dates is to calculate your Sales Tax Deduction on your Federal Schedule A (missing one day will change this deduction by only a few pennies.).
