Turkish is not an official language of the EU.

Not every national language of EU member states is an EU official language. Luxembourgish and Turkish are national languages of Luxembourg and Cyprus respectively but are not EU official languages.

EU official languages are specified by the EU treaties. In cases of enlargement, they are negotiated between the EU and the acceding state. When Cyprus joined the EU, Cyprus and the EU agreed that Turkish would not be added to the list of EU official languages.

(Also, the fact that Turkish is a minority language in BiH is of little relevance. BiH is not an EU member state, and most minority languages of EU member states are not EU official languages either.)
