I'm here to help clarify things with matching expenses, @SKH1980.
When you enter the transactions manually, the total expense will match as long as it has the same amounts and dates.
If you're using online banking and the transactions were added incorrectly, I suggest contacting your bank. This is to further check since transactions downloaded inside QuickBooks will depend on what your bank would share.
I've also added this reference for additonal information: Categorize and match online bank transactions in QuickBooks Online.
