Paid out terminated employee due SH contribution

This problem has probably been answered.  Today I learned that a plan participant terminated during the year and the financial advisor rolled out the balance to an IRA.  Little did they realize that the participant is due a SH contribution in addition to a NEC employer contribution.  Do they need to re-establish an investment account and roll the funds over or can the contributions be directly paid to the rollover IRA?

The contributions will definitely be made to the plan, not the participant's IRA.

That is how it will be done.  Thanks.
