How to remove all whitespace and newlines?

seems to work fine Try this, assuming you don't want to overwrite the old file. Easy to adapt if you do:
oldfile = open("EXISTINGFILENAME", "r")
data = oldfile.read()
oldfile.close()
stripped_data = data.lstrip()
newfile = open("NEWFILENAME", "w")
newfile.write(stripped_data)
newfile.close()

OSX sed newlines - why conversion of whitespace to newlines works, but newlines are not converted to spaces

this one helps. Your question appears to be "why doesn't the reverse of the original approach [of converting spaces to newlines] work?".
In sed, the newline is more of a record separator than part of the line. Consider that $, the null at the end of the pattern space, comes after the last character of the line, and is not a newline of every line.
printf 'foo\nbar\nbaz\n' | sed -n '1h;2,$H;${;x;s/\n/ /gp;}'

Regex to remove newlines not followed by specific string

it fixes the issue perl -pe ... works with one line a time, so a multi-line regular expression won't do you any good.
The -0 switch to Perl can change your input record separator (what Perl's notion of a line is) and allow you to operate on the entire input as a single string.
perl -0777 -pe 's/\n(?!"INC\d{12})/ /g;' test_input_so.txt
