Hi there. QuickBooks allows you to view the changes that happened to your account using the Audit log. This tool provides you with a list of changes/transactions that were made. With this info you can recreate transactions that were deleted on the account.  Here's how to use the Audit log:

1. Go to Settings ⚙ and select Audit Log.
2. Select Filter.
3. Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
4. If you've recently created these transactions, locate them on the Audit log screen, click on the blue link to open the transaction in question and retrieve the required info.
5. Select Apply.

Let me know if this info is helpful. I'll be a message away in case you need anything else.
