I marked "C" on Form 1310. I filed electronically. Do I still need to sign hard copy of 1310 and send it to IRS in mail to address where I would have mailed taxes if I had filed by mail? Thank you. I have original death certificate and Power of Attorney over all Dad's financial affairs including taxes. Do I need to do anything else? Thank You Kathleen [PII removed], esq. [phone number removed].
