The IRS does not have any form numbered 5496.
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.
For
information about how to enter your IRA contributions into TurboTax, please see

Roth IRA?":
