Overfunding a simple IRA

[chas0327]

I received a 1099R from my investment company for mistakenly overfunding my simple IRA.  The 1099R was sent as a distribution.  Do I need to amend that return and how do I do that?  Do I simply add it as an additional 1099R or is there more to it?

We need more details on what you did, and when.  Also, what code(s) are in box 7 of the 1099-R?
