How do I edit a payment amount to a supplier? (It hasn't been reconciled yet)

Sorry, I think I've just done it!

Trying to do 12 months of accounts after not having used QB since last year. (Not the best way to go)

Hello there, @nicky6.

I'm glad to know you're able to figure this out on your own. I know it'll take time to familiarize the features and options if you haven't used QuickBooks for a long time.

If you need a reference, I'll share the steps and a screenshot for your visual guide. You can use this anytime you need guidance with the process in the future.

Here's how:

1. On the left navigation bar, click Expenses.
2. Search for the bill payment. 
3. Select View/Edit. 
4. Make the necessary changes. 
5. Hit Save and close.

Additionally, I've attached an article you can use to learn how to modify transactions in the account registers: Find, review, and edit transactions in account registers.

Let me know if you have further questions about managing transactions, like the supplier payments in QuickBooks. I'll be more than happy to help.
