This does not work at all. The Box 1e and the value for it are on different lines, totally unrelated to each other. So there's no possibility the regex can make any matches.
Here you can see a sample why can't work.
Box 1e.
Box 1f.
Box 1g.
Box 2.
Box 4.
Box 5.
Box 7.
Box 12.
Box 13.
Box 14.
Box 16.
FATCA filing requirement
Applicable checkbox on Form 8949 B ..
$24.49 $0.00 $0.00
The $24.49 is what we're after, yet it appears on a totally unrelated line from Box 1e.
