Hi SS404,

Thanks for posting in the Community!

Let's try to log in to incognito window or use a different browser to select a bank account to record the GST refund. A private browser/incognito window does not store any activities, which is why it's a good idea to use it for any unexpected behavior in the program.

Here are keyboard shortcuts you can use depending on the browser you're using:
 

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Internet Explorer: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If it works on an incognito window, please clear your browser's cache. Once done, we can record your GST refund by following these steps. 

1. Go to GST.
2. Under To Pay, select Record Refund.
3. Select the Account the payment will be deposited into and the Date of the refund.
4. Input any Memo for the transaction.
5. Select Save.
