Short answer: The IRS says that if your 1099-DA has incorrect information you should request a corrected form from the issuer ("Filer" on the form), keep it with your records, and report income from the corrected form as you normally would; the IRS can't correct it. If you've already filed and the corrected form changes your income, the IRS says you generally file an amended return (Form 1040-X) if there's a change in your income, deductions or tax liability, though you don't need to amend just because the IRS corrected errors.
Timing (IRS)
- To claim a refund, you generally must file an amended return within 3 years after you filed your original return or 2 years after you paid the tax, whichever is later (if you filed early, count from the April deadline).
- Special rules exist for some situations (disasters, bad debts, etc.).
Practical steps (not advice)
- Compare the corrected form with what you reported (proceeds, basis, dates).
- If your return used your own records and they still hold, check whether anything changes.
- If something changes, complete Form 1040-X with the changes; software can e-file it, per the IRS.
- Keep both forms and any correspondence.
