The paternal haplogroup is determined from the Y chromosome, which is only present in males. Therefore, if you are female by birth, you will not have the Y chromosome in your genetic information and, as a result, you will not be able to see your paternal haplogroup in your DNA test.
However, you can still find out your paternal haplogroup if a male in your family (such as your father, brother, or grandfather) takes the DNA test. The Y chromosome is transmitted only from father to son, so his analysis will allow you to know the paternal haplogroup shared with him. Please note that sons in your family will also have their father's paternal haplogroup, but you will not be able to know yours through them.
Even though you cannot see the paternal haplogroup directly in your results, your father has left his genetic mark on you through other chromosomes (such as the X chromosome and autosomes), which are used for ancestry analysis and allow you to know your genetic origins, both paternal and maternal.
