sed -i '/\/opt\/new1/d' file_entries.txt
should do it. Just for the match, we do not need, the tailing ".*$" (because it matches always).
Actually, you want to use /^\/opt\/new1[ \t]/d because otherwise it will also delete lines that contain /usr/opt/new1 and /opt/new12. So you want a pattern that matches ^ anchor at start, the actual /opt/new1 pathname, and then either a blank or tab whitespace....
