Welcome aboard to the Community. I can share some information about how you can correct receipts in QuickBooks Self-Employed.
When you add a receipt from the Transactions section, QuickBooks scans the information and enter the details on your behalf. If you see the Needs action prompt, then yes, you can select it to review and correct the details.
In case you're unable to make changes to the labels, I suggest you exclude the transaction and re-enter it manually. Please follow these steps:
On the left navigation bar, click Transactions.
Search for the transaction.
Click the arrow pointing to the right.
Put a checkmark on the box beside Exclude this transaction.
