I tried e-filing 2019 amended tax (1040-X) return but I am getting an error stating that the SSN had been used before. How do u e-file amended return?

For what it's worth, these are the official instructions from Intuit:

Same here:"Duplicate social security number". Deleted SSNs from original return. Same error.
