TurboTax (TT) uses the 100% (110% if needed) method, because it is the IRS "safe harbor" method. That is what you are initially "offered," in TT. You are then asked if you want to "adjust your income or deductions". If you answer yes, you will be given the chance to enter your 2025 estimates and calculate estimates based on that. At end of that interview, you will be given the choice of the three methods. TT will pre-check the 100% /(110%) box.
I'm not familiar with California. But, the three states that I do prepare work similarly.
