Where do i enter form 5498?

You don't need to enter information from your Form 5498 (IRA Contribution Information) into TurboTax - generally you will find the information you need to enter into your return about your IRA contributions on Form 1099-R. There is no filing requirement for Form 5498 - just retain it for your records

A form 5498 is an informational form only and is not entered on a tax return.
