A warm welcome to the QuickBooks Community forum, @cm810. I'm here to help you locate your transactions in the vendor transaction list.
If your transactions were downloaded from the bank, make sure that you have selected the correct payee and category. You can verify this by going to the categorized section of the bank transaction.
Once you have confirmed that everything is correct, filter the transactions on the vendor profile.
Additionally, you can run a vendor report to see all payments you made to them.
Let me know if you need further assistance in locating your transactions in the program. We'll be here to lend a hand.
