Because of the confusion that can occur when the IRS changes your refund...for some reason or other, I usually recommend just taking the refund, then making the 1st Qtr estimated payment separately yourself.

But to answer your u question...after you are completely done entering all your data, and you are sure you are getting a refund, you'll find the option to apply all or part of it to 2025 taxes....as one of the selections on the menu page for :
<Federal
<<Other Tax Situations
<<<Apply refund to next year
