The main discrepancy is that these have different survey populations.

Turban's study is based on an survey (which was also conducted online) of people who, for the most part, currently identify as trans, of which some had temporarily detransitioned in the past. Whereas Littman's and Vandenbussche's studies only surveyed detransitioners who no longer identify as trans.

What these suggest in aggregate is that these populations generally have quite different reasons for detransitioning.

The study I linked has 2200 detransitioners, an order of magnitude above the ~240 or the 100 you've referenced.

What the studies kind of suggest more is that if you pull your sample from somewhere like a detransition website you're likely to get a biased result which doesn't map to the sentiment of the larger population.

No, the study you linked had ~2200 respondents who had temporarily detransitioned but later went back to identifying as trans.
