Bug in Estimated Tax Payment calculation

[Cmbmichael]

When I tried to calculate my estimated tax payments, Turbo Tax used last year's actual 2025 withholding instead of this year's 2026 withholding that I manually entered into the Easy Step software.  I was unable to overwrite this number directly into the Estimated Tax Payment Options form and will have to do the calculation manually.  Beward that this form may give you the wrong estimated tax.
