Received IRS letter for Crypto. 6174-A

Hi guys, I just received a letter from the IRS, letter 6174-A in March 2025. I believe I have reported all my crypto transactions with my CPA. Ive been reporting them for years. I'm not sure what to do with this letter as I think I have correctly filed everything. Is there a 1099 issued to me that I'm not aware of? Or an account that was stolen in the early days? I'm not sure what else to report or say to the IRs. Will be talking to my CPA this week, just want to hear everyone's experience when they received this letter. Thanks in advance
