I really don't know what TT's problem is. If you go to IRS.GOV and search for form 1310 you will see that the IRS updated it on December 2021. I have the same issue with my deceased sister. Never married and no kids. I think I will print it out the main return on TT and then go to the IRS site and fill in the blanks on Form 1310 and mail everything in. Faster than waiting until March 4th 2022! Don't have much faith on an e-file for a deceased relative anyway.
