That's OK @Jack_M , I don't understand why my solution works (for me) either 😀. I should not be choosing W-4 on that first question of this section as I am Estimating. I do not have any withholding from any of my 2026 income sources like I did in 2025 as I have now retired and wanted to do this first year of retirement doing strictly estimated tax payments. It seems like the easier way to do this. But doing it this way did zero out the 2025 withholding for me when I filled out the Pay Period questions with zeros. The questions really don't directly deal with any withholding so it is odd these zero out the 2025 withholding on my "Est Tax Option" form. It is odd it didn't do the same for you. But I did leave it selected as W-4. TurboTax really needs to clean this up.
