Form 5498, IRA Contributions Information
Form 5498 reports your IRA contributions to the IRS. Your IRA trustee or issuer – not you – is required to file this form with the IRS by May 31.
The copy you receive in the mail is for your records and does not need to be filed with your return.
Since the Form 5498 is for informational purposes only, it does not need to be entered into TurboTax. More info about Forms 1099-R and 5498 are available at the IRS website.
