After you file

that's now how it works. with $52K in AGI you must reduce the medical expenses you paid in 2022 by 7.5% of AGI or $3.9k. that leaves $19.1 that's a deduction.  $52K- $19.1K leaves you with taxable income of $32.9K of

taxable income. It will be even lower if you have other itemized deductions.

as a single individual your Federal taxes would be about $3700 on $32.9K.  Turbotax will automatically reduce the medical expenses you enter by the 7.5 %
