Different people would interpret this differently, and there is no generally accepted rule (as the fact that you have asked the question indicates). Of the two suggestions you offer, I would prefer the former. However, to avoid ambiguity I would reword it altogether and say something like 'around the year 1900'. Sometimes the context makes it clear - if you have been talking about the 1890s then say 'at the turn of the 19th century' it will be obvious that you mean 19th to 20th. (You could drop the '19th' altogether in that case.) Other constructions may be clear but they read a bit clumsily: 'the turn of the 19th/20th century'; 'the turn of the 19th/20th centuries'; 'the turn of the 19th to 20th century'. Better to reword, I think.
