Don't worry, I'll be happy to share more info and make sure you're on the right track with achieving your goals. 

You can edit an existing invoice by clicking on Sales > Invoices > locate and open the invoice in question > from here you can edit your invoice accordingly so it reflects the correct total that's derived from your invoice line items. Once you're done, make sure to save your changes.
