I have paid back my bounce back loan in full within the same tax year I took it out.How do I account for it in QB?

I'd be pleased to help share some information on how a loan works in QuickBooks Online, leebarker.

You can enter the loan in QuickBooks Online by recording a journal entry transaction (JE). However, using this method (JE) needs the assistance of an accounting professional for the accounts you need to use. They can also help and guide on which account to debit and credit.

Below are the steps to complete the process:

1. Click + New. and select Journal entry.
2. On the first line, select the liability account you just created from the Account dropdown. Enter the loan amount in the Credits column.
3. On the second line, select the appropriate bank account from the Account dropdown. Enter the same loan amount in the Debits column.
4. Hit Save and close.

For your reference, you can take a look at this write-up: Set up a loan in QuickBooks Online. This will provide you with the step-by-step process of handling a loan.

Should you have any other questions, please let me know. I'd be more than happy to help.
