what do I put on line 7

[Critter-3]

Nothing ... you can print, ink sign and mail one in yourself  or  if you are overseas/military you can still file one thru the TT system... just follow the screen instructions.   Otherwise you are too late to file an extension now.

Line 7 is for the amount you are paying the IRS for estimated taxes owed to the IRS ... read the instructions:
