If any one has been successful to efile 1040X (TY 2020 and beyond ) which other tax preparer e-filed original return and  transmitted by other tax software. Please share info here 

I followed instruction : It created more problems of duplicate SSN and duplicate file 

I called support team to get help , she (support line person) said the Professional Proseries has not yet supported this feature and she apologized for the post . She will raise the issue to upper level to correct it 

Thank you everyone
