What account on cash payment screen would I use to debit.I already know I would use cash $7,819.77 to credit as my second entry.my choices are sales salaries expense,office salary expense,and payroll tax expense

To the best of my knowledge (even though this is an old question), you would actually debit salaries payable. The key word here is "Paid cash on liability... " Which means you are paying a liability. A way to verify this would be to look in the trial balance report and see which amounts match.
