If the US itself issued the Red Notice against me, can I still enter the United States to challenge it?

Entering US territory to contest a US-issued Red Notice is extremely high-risk and generally inadvisable. Upon arrival, you would be subject to immediate arrest on the underlying US charges — the Red Notice merely extends the reach of an existing domestic warrant. CCF challenges to US-issued notices must be conducted from outside the United States. If successful, deletion removes the international alert but does not affect the validity of the underlying US warrant. Separate negotiations with US prosecutors regarding surrender terms, plea arrangements, or case dismissal require coordination with US criminal defence counsel.
