I was told I need a verification letter and I haven’t received anything

• You may receive a Letter 4883C from the IRS asking you to verify your identity within 30 days.
• Follow the letter’s instructions to verify your identity.
• Call the toll-free number provided in the letter.  You must have the letter with you when you call the Taxpayer Protection Program.
• Have a copy of your prior-year tax return, if you filed one, to help verify your identity.
• Verify your identity.  If you are unable to verify your identity with the customer service representative, you may be asked to visit an IRS Taxpayer Assistance Center in person. https://www.irs.gov/help/contact-your-local-irs-office You should plan on providing picture identification plus the letter and a copy of the affected tax return if you did file one.
