A friend of mine filed his taxes. He does est. tax payments. He was expecting large refunds. He files paper, not E-file. Two weeks later he got his State refund. It was much less than expected and he learned that he screwed up his statement of prior est. tax payments. He claimed much more.
Question: Should he file an amended X return, or just leave it be with the assumption that the Feds will pick up on that and send him the correct (lower) refund?
What to do?
