I received a 4883C letter in the mail. I mailed my 1040 tax return a month ago. I have been a victim of ID theft in the past. What questions does the IRS asked when Call the phone #? Because I worried if someone stole my identity and filed a 1040 already before I mailed mine. When the IRS asks to confirm my identity and if I filed a return and I say yes? How do I know if I am confirming my 1040 and not a fraudulent 1040 already filed by someone else? What questions does the IRS exactly ask?
