Welcome to the Community. I can help share information about recording transactions in QuickBooks Online.
If you're referring to the transactions that are automatically recreating, I recommend checking your Recurring List. You can delete them from there and manually record through the Plus sign found in the upper-right corner.
Here's how:
Click the Gear icon in the upper-right corner.
Below Lists, select Recurring Transactions.
Search for the transaction you want to delete.
Click the drop-down arrow below the Action column.
Select Delete.

If what you meant are the fields auto-filling on your forms, I recommend configuring your settings through these steps:
Click the Gear icon in the upper-right corner.

Go to Advanced.
Below Automation, turn off Pre-fill forms with previously entered content.
Click Save.
Click Done.
