I eFiled my taxes on the 1st of Feb and the very next day, I received a CSF1099R from the Office of Personnel Management for ~$300 I received as a "death benefit" from my father's employment with civil service. I had no idea this was coming. I recall prevously receiving a lump sum pymt in this amount from OPM as a "lump sum death benefit"...not sure even why, it's such a small, odd amount. My question is, since I eFiled already, can I eFile an amendment or does that need to be mailed in? It seems silly for such a small amount the but right thing to do is add that ~300 dollar into the mix.
