I already amended my 2023 tax once but now I realized another mistake which associate with my 529 withdraw. Can I amend the 2023 tax again?
Since there is no sheet of detailed calculation on the spending of 529 fund attached to the original tax form, I cannot tell where is the problem which led to an additional income from "excessive withdraw". But, I can show the calculation that I actually withdraw less than what I can. The question is how to make the amendment to show the correct calculation and what forms need to be modified in order to make the tax amendment.
