In the form "Estimated Tax Payment Options" the box with an "x" in it has the description "100% (110%) of your 2024 taxes (prior-year exception). There is a dollar amount which does not equal either my 2024 taxes due nor 110% of my 2024 taxes due. I tried a lot of variations such as eliminating the small tax credit I had etc. but no calculation matched what is displayed. The amount displayed was $137 higher than 110% of the 2024 taxes due (my AGI requires me to use 110% not 100%). Any ideas how Turbotax is finding this number? I also printed all the forms to a pdf file, then searched the pdf file for the amount shown by turbotax and could not find it on any other form except for "Estimated Tax Payment Options" worksheet.
