This is how to enter your Traditional IRA contribution:
Actually you are asking about form 5498. Form 5498 reports your total annual contributions to an IRA account and identifies the type of retirement account you have, such as a traditional IRA, Roth IRA, SEP IRA or SIMPLE IRA. Form 5498 will also report amounts that you roll over or transfer from other types of retirement accounts into this IRA.
This is an informational form and is not a tax document that you report in your tax return.
