Is this the form that has an asterisk which says that the tax rate is based on AGI? If so, ignore it.
If you had $10,000 in earned income and $400,000 in capital gains, MFJ, it would tell you you're in the 32% bracket due to $410,000 AGI. You're not. $10,000 in earned income puts you in the 0% bracket, below the standard deduction. Your capital gains would be at a marginal 15%.
It doesn't even attempt to make it an accurate number
