Tried to reconcile account, saying I have a discrepancy, a transaction which has been deleted but still can view it on account?

You can view the details of the transaction, @LizaM1.

You’ll want to open your Audit log and view the details of the transaction that has been deleted. The Audit log tracks your company activity. There, you can see who made some modification and what they did to your account.

That being said, you can see the information of your deleted transaction and recreate it if needed. Let me show you how:

1. Go to the Gear icon.
2. Select Audit log.
3. Click Filter.
4. Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
5. Click the Show only these events and select Transactions.
6. Select Deleted/Voided Transactions from the Show drop-down menu. 
7. Then click Apply.

Locate the deleted transaction and copy the details in recreating it. You can also check this article for more details: Use the audit log in QuickBooks Online.

Once everything is all set, you can now confidently start reconciling your account. To be guided through the process seamlessly, you can refer to this article for reference: Learn the reconcile workflow in QuickBooks.

Thanks @JasroV , the only problem is that the transactions isn't showing as a deleted one when I look in the audit log but when I look in the reconciliation report it is saying it has been deleted?

Great, thank you @MJoy_D  this seems to have resolved the issue.

Many thanks for your help!  You guys are always so helpful
