3 Returns created and all are "Mail-In" Instructions and Paper Copy

I am transitioning from years of CPA prepared returns (thru 2023) to TT Premier in 2024.   I have entered information for 3 tax returns;  1 for me/my wife (MFJ) and 2 for my adult children (Single).   After saving all 3 returns, I noticed Filing Instructions are for "File by Mail".   I was planning on filing electronically and having either debit/credit to/from the bank account(s) depending on the results of the tax calculations.

 

I did NOT see a step / menu selection that asked whether I wanted to file paper or e-file and may have missed it in the step-by-step process.  I do see the Electronic Filing drop down menu under the File tab.  Is this where I select "File Electronically"?

 

If yes, does this change the information in the Forms AND can I go back to edit / change any Forms if necessary after this selection?

 

Also, where do I enter the bank routing number / account information AND select the option for use of this bank information for both payment or refunds?
