Don't confuse itemized deductions on schedule A with your business expenses/deductions on schedule C. They are separate. For Schedule A personal deductions, you get to take your itemized deductions or the standard deduction, whichever is larger.
There is no min amount or standard amount for schedule C business expenses. You get to take both your Standard Deduction or itemized deductions on Schedule A and all your business expenses on Schedule C.
Do you think you have enough deductions to itemize? Some deductions are limited.
For 2019 the standard deduction amounts are:
Single 12,200 + 1,650 for 65 and over or blind
HOH 18,350 + 1,650for 65 and over or blind
Joint 24,400+ 1,300 for each 65 and over or blind
Married filing Separate 12,200 + 1,300 for 65 and over or blind
