There are some possible reasons why transactions may not be linked to invoices, Lil_miss_amy87.
This could be due to an expired bank connection to QuickBooks, unsynced feeds, or delayed processing by your bank. You can refresh the connection and ensure that pending transactions are posted. For older missing transactions, you can upload a CSV file from your bank. Additionally, verify that the date range covers the invoices you're searching for. If you recently updated your bank login credentials, make sure to reconnect your account to QuickBooks.
