Thanks for the reply but I'm not sure that the issue has been resolved. I actually started the return using the process you suggested before posting my help request.
However, since she had passed away in 2016 (as filed last year, 2017, for the 2016 Return), I was unable to proceed forward with the change for the 2017 return - the date preceded the current tax year. I've attached the error message to my original post.
I appreciate your help and thanks for your assistance.
