Should I put the a code number for box 7 on the 1099r form?

[DoninGA]

If you did not receive a Form 1099-R then you have nothing to enter on the Form.

Did you have a distribution from a tax deferred retirement account or received pension income?  If so, you will have to contact the payer of the income to get a Form 1099-R.

All properly prepared Forms 1099-R have one or two codes in box 7.  you must enter on TurboTax's 1099-R form whatever codes are shown in box 7 of the Form 1099-R provided by the payer.
