What do I do if I have already submitted my taxes and someone is wanting to submit a very late 1099 form on me?

When you get the 1099, if you have not already reported the income, then report it on an amended tax return. If you knew that you had the income in 2016, then you should have already reported it whether you got a 1099 or not. It is solely your responsibility to report all of the income that you know that you have.
