You can go to the Categorized tab from your Banking page and then click the link next to Added to: under the Added or Matched column. That will open the Bank deposit page where you can see the transaction details of the split amount.

2. Select the bank where this transaction is coming from.
3. Go to the Categorised or Reviewed tab and find the transaction you split.
4. Click the link next to Added to: under the Added or Matched column.
