When efiling Form 1310 with a Final Form 1040, do I need to upload a Form 1310 with a signature. When I go to efile the deceased person's Form 1040, TurboTax includes the filled-in Form 1310. But (like the Form 1040) , there is no manual signature. Will the IRS accept this? Or I need to attach a From 1310 with a manual signature?
