Actually I have this exact question. Kind of. I filed my mother's 2019 return (as I usually do, as her) in 2020 , 2 months after she died. The return was accepted but the refund from that year has still not appeared.
I opened the TurboTax 2019 return to try to amend it (to get it to add Form 1310), but there doesn't seem to be a way for me to indicate she is deceased (in the amended process). Is there a way I can manually add a Form 1310?
