My mother passed away in 2021, so 2020 will not be her final return, and I'm in PA, by the way. I have completed my mother's Federal 2020 return, stating her date of death in 2021, and was prompted by TT to fill out Form 1310, indicating I am to be the person claiming the refund that is due. I have been reading conflicting info as to whether I may e-file the 2020 Federal return, which will include Form 1310, OR if I should mail in a paper return and enclose a signed 1310. I know the paper return will take much longer to be processed, but am concerned that if I e-file, the return may be rejected. And/or does it make any sense to BOTH e-file and mail-in file a paper return with the Form 1310? Please advise asap. Thanks in advance.
