I used the formula above to calculate the earnings, but I am not sure where to put that into TurboTax. TurboTax knows the amount of my excess contribution, but it never asks me about the *earnings* on that excess contribution. When I leave "step-by-step" and go into the form view, it will not let me type into Form 8889 boxes 14a and 14b where it seems like that information should go per-IRS instructions.
