The only thing I'm thinking with sending it in ASAP is it starts the clock on when they received notice as to eliminate any time lag in notification of the error (shows diligence?). I know the stand alone is used on prior years for each RMD missed... with 2017 I could wait and file by tax time. However I will likely have to override the value in TurboTax which may open it up to more scrutiny? Sending in a stand alone once forms get finalized may have the whole thing resolved by the time I filed in April... either way its a smallish amount $460 that makes up the RMD so it shouldn't affect taxes... just want the 50% Excise waived and keep things as simple as possible.
