Retirement tax questions

Please be aware, since you didn't take out the excess amount by April 15th, you are taxed twice on the excess deferral left in the plan.  This happens once when you contribute it (with the steps below) and again when you receive it as a distribution. You can't include the excess amount in the cost of the contract even though you included it in your income.

You will have to wait until your return has been processed and then amend your tax return to add the excess deferral to your wages with these steps:

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 "2022 Excess 401(k) Deferrals" for the description, enter the amount and click "Done".

Since you missed the deadline you can check if your plan allows keeping the excess in the plan until you are 59 1/2. Then you can avoid the 10% early withdrawal penalty.
