Missed Payroll

I am about to enter my January 2018 payroll, but I am off for one employee.  When I investigated, I noticed that a payroll was missed in October 2017 for that same employee.  I have done 6 payrolls since then, but does this mean i have to delete the 6 payrolls and redo everyone from November to December, including the missed one so that everything balances, or is there an adjustment I can make.  Please help.
