Welcome to the Community, @dougwalker. Let me share some details regarding your concern.
If you are using QuickBooks Online, I suggest setting up an expense or asset account when recording an expense or check. You can also reach out to your accountant to verify the correct way to do it.
If you're using QuickBooks Self-Employed (QBSE), we can categorise it as a personal expense. Same situation as above, you'll need to consult your accountant for the accounts to use.
