Can I do automatic withdrawal for my Form 4868? I have the bank information entered but TT is saying I have to print and mail the extension. Thanks.

Yes! When you file your extension through Easy Extension, we give you the option to pay your federal (IRS) taxes using either direct debit or check. 

If you pay your taxes with direct debit, you'll need to provide your 2022 AGI for verification purposes. If you didn't file a 2022 return, enter 0 for your AGI.

Here's more info on Paying Tax With Extension.
