I received a letter 12c requesting 8962 but now I want to make changes to my income as well. What should I do?

After you file

Refile your return with the 8962 and your revised income

Do you mean file an amended return 1040X? Or reply to the letter with form 8962 and 1040 showing the new income?

Better chat with a Turbo Tax expert to get a reliable answer. I did mean file an amended return.
