How to change my 2020 tax refund payment to direct deposit before e-file?

I used TurboTax Deluxe for years, for 2020 tax return, it's troublesome trying to change my refund payment. In the final form, I cannot update and set the direct deposit numbers. Going 'File' and reopen my return, I searched all under tabs 'Personal Info' and 'Federal Taxes' and I was unable to find anywhere to fill it up.  Please advice.
