You've come to the right place, @gpwelding.

You can either write a check or record a credit card transaction to add your expenses manually to QuickBooks Desktop Pro Plus 2021. I can guide you on how to do it.

Here's how to write a check:

1. Go to the Banking menu.
2. Select Write Checks.
3. Choose the Bank Account where the actual payments are posted.
4. Set the date of the transaction.
5. Enter the name of the Vendor from the Pay to the Order of field.
6. Pick either the Expense or Item tab.
   • Use the Expense tab to enter shipping charges, liability (in cases of payments for liabilities/loans), and other expenses not associated with any item in QuickBooks.
   • Use the Item tab to choose the appropriate item on the drop-down list.
7. Enter the expense transaction details.
8. Click Save and Close.
