Excess Roth 401k contributions

I've seen a few different threads on this but still unsure of how to handle. 

Due to switching jobs in 2025, I ended up with an excess Roth 401k contribution of $292.

The excess contribution happened in Dec 2025. I realized it in January 2026. I notified my current employer, and a correction/reimbursement request was submitted to the 401k administrator in January 2026.

 

Note: this is an excess Roth 401k contribution, so the $292 should already be captured as income for 2025.

 

I received a refund check of $291 in February 2026. The check amount is $1 less than the contribution amount given losses.

 

There is a notice accompanying the check - it states that the refund information needs to be added to my 2025 taxes. It also states that a 1099R will be sent out in next year (2027) to be filed with my 2026 taxes.

 

Here’s the information that I received along with the check:

  • Excess Deferrals: $0.00
  • Amount of Refund: $291
  • Contributions Already Taxed: 292.00-
  • Taxable Amount: $0.00
  • Roth 401k Contribution Amount: $292
  • Roth 401k Earnings Amount: $1.00-
  • Roth First Contribution Date: 2025

 

TurboTax has already flagged that there is an excess contribution of $292 on my 2025 taxes. TheTurboTax software suggests that I create, and enter, a substitute 1099R for my 2025 taxes.

 

Is this accurate? If so, 1) what code do I use for the substitute 1099R that i'm creating?  2) which numbers from above go where on the substitute 1099R that I need to submit this year?

 

Note: When I get the official 1099R next year (2027),TurboTax also suggests that I enter its information on my 2026 taxes.
