I’d like to deduct medical expenses. I don’t see an option to do that.

If you itemize your deductions, you can deduct only the part of your medical and dental expenses that exceeds 7.5% of the amount of your adjusted gross income on Form 1040 or 1040-SR, line 11.

To enter your medical expenses:

1. Go to Federal 
2. Go to Deductions and Credits 
3. Scroll down to Medical 
4. Go to Medical Expenses.
