This was an real issue during last year's filing season. My wife died in Jan 2019. When I filed I got the same TT runaround as you. The say mail the return. My solution was to use FreeTaxUSA. Easy and free. IRS took that e-file within minutes. It does involve repeating a second set of questions but much can be completed by submitting a pdf file of your return to FreeTaxUSA. I am convinced TT does not want to solve this problem. If FreeTax has it solved surely TT can too.
