You can check the status of your online application via My Activities. Once your cash top-up and/or CPF transfer application is successful, you will be able to find the details of the transaction on your Retirement Dashboard under the "Retirement Sum Topping-Up History" section.

If you have submitted multiple applications, you can also review the status of each application under My Activities. This will help you identify which transactions have been successfully processed, and you can also submit a new application if necessary.
