I have a new client this year who brought in a 1099-R that has a distribution, as well as withholding, which is in the  name of an Irrevocable Trust. The recipients TIN, is NOT my client's SS #. My understanding is that this should be reported on Form 1041, however it looks like this has never happened with their prior accountant, this 1099-R was reported on their Form 1040. I am not a trust expert, however based on my research, I do believe they have been reporting this incorrectly, especially since there is withholding. Any advice on this would be greatly appreciated!
