I forgot to claim my EIP for $1200 on my 2020 taxes, so i need to file 1040X amended tax return, what do i need to include when i file 1040X? Do I need to include a copy of my 2020 tax return that i originally filed? Also my EIP was sent out as a check which i had sent to my mothers address and i later found out she tried to deposit it into her bank account but it got voided, she is now deceased what do ineed to say or include when i file my 2020 1040X form?
*i used freetaxusa to file it by paper.
