If I put some bills I paid for medical professionals under the Expenses section, can I also include them in the deduction and credit section?

Personal medical bills  should NOT ever be entered on the Sch C ... they are ONLY to be deducted on the Sch A. 

You do not enter payments to doctors or any other medical professional as an expense on your Schedule C.

Those expenses are only entered on Schedule A as an itemized deduction.

 Actually medical bills do not go in business Expenses.  They all go on Schedule A under Deductions & Credits.  Not schedule C.  

You can only enter Medical Insurance Premiums as a business expense.  And even then Self Employed health Insurance does not go directly on Schedule C so it will not reduce your Net Profit or self employment tax.

Self-employed health insurance deduction goes on Form 1040 Schedule 1 line 16 then to 1040 line 8a, as long as the expense is not greater than your net self-employment income. If it does exceed your net self-employment income it gets split automatically. An amount equal to your net self-employment income goes on Form 1040 Schedule 1 line 16, and the remainder gets added in to medical expenses on Schedule A.

BUT do not enter any Health Care Marketplace insurance you bought.  If you enter the 1095-A and select the "Self-employed and bought a Marketplace plan" box, it will automatically include those premiums in the SE Health Insurance section.  So you shouldn't enter it again on schedule C.
