There some criteria that could prevent the program from matching. Kindly check these:

Verify the transaction first.
Make sure the QuickBooks Online transaction has not been previously matched to another transaction.
Once you add the receipts and bills in QuickBooks, they’ll show up in the For Review tab where you can review, edit, and match transactions. The receipts tab is where you can manage to match your expense receipts and bills all in one place.
