Hello @Sandy Eggo,
Let me help share how you can change the account and name settings of your downloaded transactions in QuickBooks Desktop For Mac.
Normally, all details of your downloaded transactions are based on the information provided by your financial institution.
With this, I'd recommend contacting the Technical Support of your bank so one of their specialists help you map the accounts and names of your transactions accordingly.
Additionally, I've also included this reference for a compilation of articles you can use while working with us: Banking - QuickBooks Desktop for Mac.
If there's anything else that I can help you with, please let me know by leaving any comments below. I'll be here to lend a hand.
