Made an overcontribution to 401k

It looks like I have made an overpayment to my 401k. I am contacting the retirement program manager and they will email me a check with the extra amount. They mentioned I should be able to mark in turbotax that I have fixed the problem and that the IRS should expect next year to see 1099 with the extra payment. How can i do that in turbotax, please?

 

Thanks,

Eliyah
