Using TurboTax Premier 2025

If you are using TurboTax Premier Desktop, you can go to Forms Mode (click on Forms at the top blue bar if you have a Windows device, or the top white bar for Mac) and look at the four vouchers that TurboTax has prepared from your entries (Form 1040 ES 1 through 4) to confirm that all four estimated payments were calculated from your entries. 

For the 2026 tax year, federal estimated tax payments are generally due in four installments: April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. Is it possible that you were looking at the three payments that are scheduled for 2026 (the 4th being due in 2027) and this is why you see 75% of the total?

See this IRS webpage for more information about Federal estimated taxes.

I am actually seeing 75% LESS of what I expect.  my estimated takes is being calculated correctly, and then it subtracts the expected withholding for 2026 on the Estimated tax payment options worksheet..  However, it is taking out an amount that does not equal the amount that I inputted for expected withholding.  So that is where the error is taking place.  I can see the calc and the deduction that is causing the error.  It does say next to the deduction "Expected withholding for 2026 (2025 actual withholding)" and then an amount I don't recognize that is 100 times more than what I input.
