BEWARE!!!!   The 1040 ES worksheet is NOT calculating correctly.  It is doubling line 2C but the doubled number does not show up on line 2C.  The doubled number is NOT correct.  It is also not giving the correct amounts on the estimated forms if 100% of 2026 is selected.  I have tried to force the number to see what changes.  NOTHING CHANGES.  USELESS WORKSHEET!!!!!!!
