My child was born and passed in 2022, and I did not request a SSN, therefore I must file via mail. I know I have to include her birth and death certificate, but does it need to be the original, or will a copy be accepted? Also, What documents should I include when filing via the mail? Do I send 1040, my 2 W2s, birth and death certs, 1098-E? That's all I used to file.
