Answer:
$1,850
Explanation:
The maximum child tax credit per qualifying child was 2,000 during 2019. But this amount starts to phase out if the single person's MAGI is higher than $200,000 per year.
It phases out by $50 for every $1,000 that your MAGI exceeds the threshold, in this case = 3 x $50 = $150 phase out.
Total deduction = $2,000 - $150 = $1,850
