Mailed a correct SC state return but forgot to include a 1099-DIV and copy of federal -- do I need to amend?
We have a situation where we always have to file our SC state return by mail, even though we always e-file the federal return. This year I calculated all our taxes correctly, but when I mailed the SC state tax, I forgot to include a copy of the federal return and a copy of a 1099-DIV that was included in our income.
Do I need to file an amended SC return?
