Get your taxes done using TurboTax

so your reporting 1/1/2022 to 11/30/2022. what you need are the December activity statements you take the 1099's and then remove the December activity. Since the 1099's have the wrong id number the IRS will probably not make an inquiry to the estate. There may not even be a reason to use adjustment codes becuase of the wrong id #.  had you asked much earlier, I would have suggest contacting the broker to correct the reporting.  the issue may be that the 1099s were issued the decedant's SSN. so there may be an inquiry. The  1041 is late. with an 11/30 year end it was due 9/15/2023
