From beginning of line to first tab, with 22 characters or more of non-tabs, replacing that tab with a soft return:

Find

^([^]{22,})

Replace

$1

(although you might want to add the tab again in the replacement line, so your next data is aligned the same as non-soft-returned lines).

It won't work perfectly; if there is a single name with lots of i's and no m's, it will broken while not necessary; and if you have a single long name with lots of m's, you'll need to spot those by eye. But I think these stand out of the crowd, and in any case there shouldn't be much of these (if there are too much remaining, decrease the number of minimal characters).
