Amend return after receiving CP024 refund correction

I received a CP24 with corrected refund. I need to correct a 1099-INT amount I submitted with my original return. 

How do I submit the corrected number - if via 1040-X  -- do I reference the numbers on my original submission as the base for the amendment or do I need to include the CP024 adjustments made by the IRS to the 1099-X amendment?
