Does not let be transmit for e-file as there is no action to complete to indicate I am not a robot?

If your "Transmit My Returns Now" button is not working, it may be due to a CAPTCHA not appearing, where one would need to checkmark "I am not a robot."

NOTE:   Are you using any ad blockers or script blockers?   If so, that may be blocking the CAPTCHA.

• First, simply refresh the page in your browser and see if that changes anything.
  
• If not, then log out and clear your browser Internet cache.
• Close the browser and reopen it.
• Make sure cookies are allowed/enabled in your browser settings so the CAPTCHA will appear.
• Log in and try again.
• If still unsuccessful, do all the above, then this time open a private window/private browsing (aka "incognito mode").
• Log in with the private window (again making sure cookies are allowed) and try the efile again.
  

After asking my question, I changed the method of filing to 'mail' and logged out of TurboTax ... gave it a few minutes and signed back in ... this time changed filing method back to e-file and clicked on continue ... this time I got the additional security action, which I did ... again hit submit and it worked ... received a notice that IRS received the tax return ... essentially, without knowing it, I did pretty much what you recommended ... Thank You so very much for the info which in turn backed up what I did!!!!

You're welcome.  You likely cleaned up something in your browser by logging out and back in.   Good luck.
