if your withholding in 2024 will be the same as 2023 the vouchers are correct. safe harbor is 110% of 2023 tax less actual withholding for 2024. Apparently, Turbotax has no place to enter expected withholding for 2024
if you want to use a number different from 2023.
you could print out the vouchers and manually change them to whatever number you like. the only effective way to get the vouchers preprinted with the withholding you want to use is to change the withholding on the 2023 forms. this will produce vouchers with the amount you want. then print them out. no need to actually use then since in my opinion it's much better to arrange payments using IRS online payment system
anyway once dome be sure that the withholding on the 2023 form is correct.
