Tax Year Prior to 2020: Problem filling out Form 2441 in Turbotax Premier

My husband (primary taxpayer) is the disabled person, and I paid dependent care using a Dependent Care FSA. I figured out how to override Form 2441, but the earned income instructions suggest a disabled adult's earned income is $3000/year, but my Dependent Care FSA contribution limit is supposed to be $5000. Does that mean I am disadvantaged in the amount of untaxed benefit because in my case the disabled person is my spouse instead of some other dependent?  Or is there some instruction that suggests the earned income amount for my spouse should be entered as $5000?
