Check your W-2 entry in the program and compare it with what's on the W-2 you got from your employer. If you have an amount in box 12 with a letter code of D, E, F, G, H, or S then you have contributions to a retirement plan.
If the above doesn't explain it, then under the Deductions and Credits tab scroll down to the Retirement and Investments section and see if you have an amount shown for the sub-section "Traditional and ROTH IRA contributions".
