Hello there, @lydbrewer.
If you've paid your employee using a physical check and let him or her cashed it out, you can just create a regular payroll. Just make sure you're using paper check for recording purposes. While, if you've paid your employee using a regular paycheck but was unable to cashed it instead you've paid her with cash. Let me share some details on how to document this transaction.
First, let's run a regular payroll:
Once completed, let's create a bank transfer in QuickBooks to account the movement of money from Cash on Hand or Petty Cash to your payroll bank account.
Alternately, you can create a journal entry to record the entire transaction. For more detailed steps, you may check this article: Create a journal entry.
