reversing payroll advance without access to payroll module

I have a balance on a payroll advance account from a previous year. I can't access the account through the general ledger even if I unlink it and make it an "other asset"

I no longer use the payroll module so everything is grey and I probably couldn't access the pay cheque anyway since it is from at least 2 years ago, prior to my joining the company.

Does anyone have a bright idea on a workaround for me?

When I look at the current year to date for all employees all is showing 0.00 other than this amount sitting there for one employee. 

I need to clear the account since it is part of cleaning up the books at this point.

Thanks for any and all help.
