Get your taxes done using TurboTax

You must include the excess deferral in your wages in the year the excess deferral happened. 

Please follow the steps below:

1. Login to your TurboTax Account 
2. Click "Wages & Income" (under Federal) on the left side of your screen
3. Scroll  down to "Less Common Income" and click "Show More"
4. Scroll down to "Miscellaneous Income, 1099-A, 1099-C" and click "Start"
5. Select "Other income not already reported on a Form W-2 or Form 1099" and click "Start"
6. On the "Did you receive any other wages?" screen answer "Yes" and click "Continue"
7. Continue until you get to the "Any other earned income" screen, answer "Yes" and click "Continue"
8. On the "Enter Source of Other Earned income" screen select "Other" and click "Continue"
9. On the "Any Other Earned Income" screen enter "2024 Excess 401(k) Deferrals" for the description, enter the amount and click "Done".

I assume you didn't have any earnings on this small amount and therefore this is all you need to do.
