Charlotte (age 40) is a surviving spouse and provides all of the support for her four minor children (ages 4, 8, 11, and 14) who live with her. She also maintains the household in which her parents live and furnished 60% of their support. Besides interest on City of Miami bonds in the amount of $5,500, Charlotte's father received $2,400 from a part-time job. Charlotte has a salary of $80,000, a short-term capital loss of $2,000, a cash prize of $4,000 from a church raffle, and itemized deductions of $10,500. Compute Charlotte's child and dependent tax credit.

Charlotte's child tax credit is 8000, of which (answer here) may be refundable and her dependent tax credit is 1000, of which 0 may be refundable.

How much of Charlotte's tax credit is refundable? (please just fill in the blanks above, I already ask this in here so many times and they are giving me answers I didn't ask I just want to know on the 8,000 of Charlotte's tax credit how much is refundable.)

Just fill in the blanks. Note: I already tried 1,400 and 5,600 and they are not correct.
