need to amend and switch to itemized deductions

I just discovered that turbotax selected standard deduction of  27,700 for 2023 instead of $41,894 so I want to amend the 2023 return.  The higher # is clearly listed on line 17 in the forms section of Schedule A.  I can't even check the box to manually force it to use itemized instead of the standard deduction.  All help is appreciated!
