How do I know if my 2020 federal estimated tax payments are actually coming out via direct debit (Auto withdrawl)?

If you marked the boxes on the 1040ES worksheet, the client letter should state that theyve been scheduled for direct debit.

You could call the EFW phone number and inquire...the phone  number is on the Form 9325

Ask your client.  Good excuse to talk to them.
