• Many songs are co-written with others like Jack Antonoff, Aaron Dessner, Max Martin. That is common in pop music. But her lyrical and melodic ideas are real and credited. 

• In some cases she wrote entire albums solo. For example, Speak Now was written only by her. 

• Taylor herself has publicly rejected claims she doesn’t write her music, saying she writes all her songs and that it is false to say otherwise. 

• Some artists and collaborators defend her writing process, saying her creative role is significant and hands-on. 

Claims like “she doesn’t write her own songs at all” ignore the official credits and her own statements.

In simple terms:
•You can trust that Swift writes or co-writes her songs.
•She is not a pop puppet with ghostwriters doing the work.
•Co-writing does not mean she didn’t write anything. It means she worked with others on parts of the song.

That’s one source …
