"Deductions: Retirement Payments" is incorrect or where did that number come from?

Where did TurboTax get the Retirement Payments amount?

[DoninGA]

Did you enter a W-2 and have an entry in box 12 with a code of D and an amount?

Code D - Elective deferrals to a section 401(k) cash or deferred arrangement.
Also includes deferrals under a SIMPLE retirement account that is part of a section 401(k) arrangement.

Or do you have a contribution to an IRA?
