What you have through your employer is almost certainly not a Roth IRA. Amounts reported with code AA, BB, or EE in box 12 of your W-2 s a designated Roth account in a qualified employer plan (401(k) , 403(b), 457(b) or the federal TSP). Nothing about amounts reported with these codes is to be entered under Deduction & Credits.
(Opus 17, Payroll Deduction Roth IRAs, while uncommon, have been around as long as there have been Roth IRAs.)
