Does my 401K qualify as contributing to a traditional IRA?

[dmertz]

No.  A 401(k) is not an IRA.

Enter amounts shown in box 12 of your W-2 only in box 12 of TurboTax's W-2 form, nowhere else in TurboTax.

No, in general, a 401k is done through payroll deductions from your salary and is handles through your employer.  It is called deferred compensation because it is not included in your Box 1 income and is not taxed now, but when you take it out of the account later.  A traditional IRA is an individual retirement account meaning it is your account.
