If the refund that your daughter received was the amount shown on the tax return that she filed, and the IRS is not asking for any payment, you don't have to do anything. The mistakes didn't affect the amount of her refund, and they won't affect future years. It's not necessary to fix them.
Sorry, my question is what do we need to do about this? Does the irs keep the paper copies or scans of the paper returns so that they can fix the problem? Do we need to file an amended return even though the mistake is not ours? WE are aware of the issue because they sent a letter to my daughter telling her that she can receive communications from the IRS in alternative formats (large print, braille, audio)
