No - you
cannot, as they are being reported
via Form W-2, as a deduction from your income. All you
have to do is report W-2 data in Turbo Tax exactly as it appears on the form.

tax, it effectively works like a tax deduction. If your employer makes
matching or other additional deposits to your account, those are also
tax-deferred and there's no need for any additional reporting.
