While Turbotax asks for medical expenses by categories, there;'s no need to detail them that way. all that's needed is one entry for all qualifying medical expenses excluding items entered elsewhere like medicare premiums, self-employment health insurance, Affordable Care Act coverage that must be entered in the appropriate place.
AGI (1040 line 11) is not affected by itemized deductions. $60K in gross income (1040 line 9)) would only be affected by Schedule 1 - additional income and adjustments to income. Line 10 increases AGI while line 26 decreases AGI. Thus if gross income was $60K and you had no adjustments to income, AGI would be $60K. 7.5% would be $4,500. If gross medical expenses were $10K, $5,500 would be included in itemized deductions.
