I posted some questions on the other site where you posted this. Need to have you clarify those questions before responding further in order determine exactly what TRP has done. Note that if TRP actually processed a disallowed recharacterization, how they would correct that or report that is unpredictable, but something that you need to have clarified by them. For example, it is not possible to re recharacterize and already recharacterized contribution, but if you made Roth contributions in addition to the $600, the fact that the $600 was recharacterized does not prevent you from recharacterizing the additional Roth contributions to TIRA. To be sure what actually happened, please clarify the questions asked on the other site.
