John and Sarah have three children (ages 5, 6, and 14). John earned $36,000 in 2019. Sarah worked part-time and earned $5,000. They had no other income. They paid a total of $4,600 in qualifying child care expenses for their two youngest children ($2,300 for each child). The 14-year-old is John's son from a prior marriage. He lives with John's first wife, but John will be claiming his son as a dependent this year. What is the correct amount of the federal Child and Dependent Care Credit?
