It will go to the employee's PF account.
There was a circular stating that if any employee would like to postpone or defer their pension, they can do so. By doing this, they would receive an additional amount of 4% if deferring the pension up to 59 years of age, or 8.16% if deferring until 60 years of age. This can be done with or without a contribution to the Pension account. For this, the member has to provide an option to the EPFO. As this facility is available, the system will show the amount contributed to the Pension account. However, when you apply for a pension and the options are traced out, the amount would be transferred to the PF account if it is found that no such option was filed by the employee.
To avoid confusion, you can write to the EPFO stating that the member's Pension account was wrongly credited by pension contribution and request that the same be transferred to the PF account. This will be sufficient.
