How to report excess deferral s 401k contribution?

[RobertB4444]

Sorry @markrocknroll - you're going to use code 8 because you pulled the money out before the tax deadline so it all counts as 2024.  And you will put the excess and the earnings in box 1 and the earnings only in box 2a.  That way you will pay tax on the earnings but not on the amount that you contributed.

I have $13 excessive 401K contribution in 2024, $13.05 was returned on 4/10/2025 (includes $0.05 earning). I am following Turbo tax instruction, faked a 1099-R and put code P, but choose 2025. In box 1, should I put $13.05 in both box1 and box 2a?

Box 1 is $13.05, box 2a is 0.05$.  Which will work out to zero.
