Long Term Care Policy Surrender Value Reported on 1099-MISC

I have received an option to surrender my Qualified LTC policy and am told that a 1099-MISC will be generated for the 2024 Tax year. I am seeking to understand the tax implications of doing so. I have had this policy for 20 years. The premiums  were paid with after tax dollars.  A rough estimation would indicated that the surrender value is greater than the premiums paid into the policy. What are the tax implications?
