PR - Additional Medicare Tax double on paycheck last quarter

SUGGESTED

There was a single payroll check the end of last quarter that for some reason doubled the medicare - additional tax deduction for an employee. When filing the quarterly 940 return it was noticed and we showed as overpayment/refund.

What is the best way to correct this for employee? Should we just reduce the "medicare - additional tax" on next paycheck to bring YTD in balance?
