If it came out of your checks pre-tax it is not deductible so you don't need to enter it. And anyway it takes a lot of medical to get to deduct any.
You can only deduct the amount of unreimbursed Medical Expenses you actually paid over 7.5% of your AGI. And then all your itemized deductions have to be more than the standard deduction to get any benefit (so you would only be getting the benefit of the amount that puts you over the standard deduction). And since the Standard Deduction is increased more people will not need to Itemize.
For 2021 the standard deduction amounts are:
Single 12,550 + 1,700 for 65 and over or blind (14,250)
HOH 18,800 + 1,700 for 65 and over or blind
Joint 25,100 + 1,350 for each 65 and over or blind
Married filing Separate 12,550 + 1,350 for 65 and over or blind
