With all due respect to QB employees, do not take their advice on this.  They are not qualified.  I know they are trying to do their jobs and someone is making sure they reply to these posts but, as you've seen, they do not appear to be accountable to whether they are actually answering the customer's question.

When you deducted the amount from his paycheck, that amount is sitting in a liability account, correct?  If so, create a journal entry to move that liability to the Lowe's credit card: debit the payroll liability account, credit Lowe's credit card.  You should now have the amount sitting in the credit card liability account waiting to be paid.
