I already have a US passport. Do I need an N-600?

Not legally; both are proof of citizenship. But a passport expires and the Certificate of Citizenship does not, and having the certificate makes future passport renewals and benefits claims simpler. Many people obtain both.

What is the difference between N-600 and N-600K?

N-600 is for people who are already citizens by acquisition or derivation, typically living in the US. N-600K is for children who live outside the US and do not automatically derive citizenship; it naturalizes them under INA 322 during a temporary lawful stay in the US.

Can the application be denied if I am really a citizen?

USCIS can deny for insufficient evidence even when the underlying claim is good. The remedy is usually more documentation, a motion or appeal, or in some cases applying for a passport, since the State Department adjudicates citizenship independently.
