That's complicated. What is the code in box 12 of your W-2?
The usual answer for this is that employer qualified plans are NOT IRAs, even though they have a similar purpose. If you have a Roth account in a 403b, or a Roth account in a 401k, that is not an IRA, and it is only reported on your W-2 (code AA or BB).
However, there is something new called a Payroll Deduction IRA. This is where your employer contributes directly to your IRA, instead of setting up a qualified plan (which can have a lot of paperwork).

This is the same as a private IRA, except some of the money comes from your employer. The contributions follow the IRA rules and limits (not the 401k rules) and are limited by income and filing status. The contributions will not officially be reported on the W-2 (they could be in box 14, which is for notes and comments, but are not in box 12). You need to report them as contributions.
So it depends on whether you have your own IRA that your employer pays in to via the PDI, or whether you have a qualified plan that you called by the wrong name.
