"Or enter federal extension payment in the Search box located in the upper right of the program screen. Click on Jump to federal extension payment"
This recommendation worked! I thank you.
Seriously though, it's a bit much to ask a user to be entering THAT phrase to get the option to enter the amount of 'estimated tax due' for an extension so it appears in the correct line on the 1040. I looked for the Form 4868 and NO OPTION was presented for entering the amount of pre paid tax already paid, just an option to file for an extension. This function needs to be consolidated for the option to enter an amount already paid.
