Any biography of Chaitanya Mahaprabhu says about Chaitanya Mahaprabhu meeting Parashurama?
Yes, here is what the Chaitanya Charitamrita says:
At Durvaśana Śrī Caitanya Mahāprabhu visited the temple of Lord Rāmacandra, and on the hill known as Mahendra-śaila He saw Lord Paraśurāma.
Here is what Srila Prabhupada says about this verse:
In Durvaśana, or Darbhaśayana (now known as Tiruppullani), which is seven miles east of Ramnad, there is a temple of Lord Rāmacandra. The hill known as Mahendra-śaila is near Tirunelveli, and at the end of this hill is a city known as Tiruchendur. West of Mahendra-śaila is the territory of Tribāṅkura. There is mention of Mahendra-śaila in the Rāmāyaṇa.
