Refund cash back into an Expense Account

Using Cash, I gave an employee $400 to buy supplies for a repair.

I created the Cash Withdrawal from Checking using the Expense Account "Repair Expenses"... which now showed in my Reports that I spent $400 this period towards "Repair Expenses".

But then, after completing the job, the employee said that he only needed to spend $230 on the repairs, and he handed me $170 to put back into the bank.

I can create a Deposit and use an Income Account like "Reimbursement Income" or "Other Income".... but that still shows in a Report that I spent $400 on "Repairs" this period.

But I didn't. I spent $230 on Repairs.     "Repairs" didn't cost me $400...  And in no way did I 'make' $170 in any sort of Income, no matter what the title of that Income Account.

On paper, I know how I could "put that money back into the Repairs Account" so that it correctly showed an outlay of $400 for a while, but then ended up with only an outlay of $230... and my Checking Account would of course come out correctly...

But how, in QuickBooks Online, do I somehow Record the "Money Back/Reimbursement" reflecting in the Expense Account?  I have no Income Account called "Repair... Reimbursement?" and even if I did, my Repairs Expense Account would still be incorrect.

If anyone can solve this conundrum for me, I'll fax you the $170....
