A Simple IRA a retirement plan provided by your employer, so it is accounted for on your W2.
Employee deferrals made through your employer are reported on your W-2 in boxes 12 with code S. Enter this only on TurboTax's W-2 form. Employer contributions are not reported anywhere on your tax return.
Do not report Simple IRA contributions under Deductions & Credits. This is for Traditional and Roth IRAs only.
Form 5498 is informational only.
Hope this helps.
