I over-contributed to my 401(k) plan in 2019 and my employer reimbursed the difference prior to 4/15/20. Where do I enter the adjustment in Wages & Income?

Reporting excess salary deferrals (excess 401k contributions) returned to you after the end of the tax year but by April 15th of the following tax year on your 1040.  Do not create your own 1099-R for this situation.

Page 10 of IRS Pub 525 under Excess deferrals (the IRS term for 401K contribution is deferral) tells us to include the excess deferrals as income on line 7 of Form 1040 if the money was returned after the end of the tax year but by April 15th of the following tax year.  You need to report only the excess contribution, not any money generated by the investment of the excess contribution.  What you earned will be covered by a 1099-R for the following tax year and will be entered then as a normal 1099-R.

Below is how to do this in TurboTax:

• Click on Federal in the left-hand column, then on Wages & Income
• Under All Income, scroll down to Less Common Income
• Select Miscellaneous Income and click Start
• Select Other income not already reported on a Form W-2 or Form 1099 and click on Start
• Answer the question "Did you receive any other wages?  Yes
• Click through the questions till you get to Any Other Earned Income
• Answer Yes to Did you earn any other wages?
• Indicate Other as Source of Other Earned Income and click Continue
• For the description enter "2019 Excess 401K Deferrals" and click on Done

Thanks. TurboTax told me to do something a little different. Please see below:

4. Report the excess deferral on your 2019 return in the Income section for Retirement Plans and Social Security whether or not you received a Form 1099-R before you file your return. Enter as much information as you can. Report the excess deferral amount in boxes 1 and 2a, and use code P in box 7. Indicate that this is a 2020 Form 1099-R.

What do I do?
