Once again-----follow the math. The whole $8400 was not "drained" because you say you are getting a refund of over $5000.
YOUR own words from above......
"...... my refund on line 35a of $5,383. ...."
SOME of the $8400 was used to pay tax due that you owed for some reason. The amount that had to be subtracted from your $8400 child tax credit will come AFTER line 28. When a particular line tells you to add some lines together---DO that and check it against the tax form. We can do no more here. If you need real-time help to follow the calculations from line 28 down to line 35a please call customer support.
