I have been appointed Administrator of my late sister's estate, and need to file her final taxes. However, I don't have any income information for her (she should have received a 1099-R), and the processing time to receive a replacement 1099-R will have it reach me after the filing deadline (probably the first week of May).
I would like to file an extension, but I have no prior year financial records for her, and no way to estimate her 2021 taxes and/or the amount of her 2021 tax payments. Is there any kind of recommended procedure for filing?
