yes neither of the question is correct. if v look for the perfect grammer sentence it would be
" what does she not like? "
but usually in speaking ppl use
" what does't she like? "
The easy way to get over the prob the simple rule is this that u take the auxillary verb (do, does, did) at the start of the sentence ( if W family is present then after it)
in the other one u asked "what she does not like" is incorrect because the "does" should't be follow the subject as explained earlier. Hope u get the point
for anyother info ,free to ask.
