The account which is not used in journal entry of the forfeiture of shares is:

The standard journal entry for forfeiture of shares is:
$$\text{Share Capital A/c}\text{Dr.}$$
$$\text{Securities Premium A/c}\text{Dr. (if called but not received)}$$
$$\text{To Calls in Arrears A/c (or individual unpaid call accounts)}$$
$$\text{To Share Forfeiture A/c}$$
The Capital Reserve Account is only used later when the forfeited shares are reissued, not in the initial entry of forfeiture itself.
