Hi SSCS2015,
If you were not getting surcharges before, it looks like that setting has now been turned on for your online invoice payments. When customers click Pay now, a card fee gets added on top of the invoice amount, which is why you see 130 dollars on the invoice, but 132.46 dollars paid. The extra bit is just the card surcharge, not extra income.
If you would rather cover the fees yourself, go to Settings in MYOB Business, then Sales settings, open the Payments or Online payments area, and change the surcharging option or turn off online payments for new invoices.
For more info on how surcharging works and how to change the setting, this help article runs through it with examples:
