You should be able to claim on Loss on schedule C. For 2019 Schedule C Net Profit or Loss now goes to 1040 Schedule 1 line 3. Then the total on schedule 1 line 9 goes to 1040 line 7a.
Is it not letting you show a loss?
Some expenses, such as home office or section 179 depreciation can only be used to reduce your schedule C taxable income to zero, and not to create a loss. Excess deductions for these carry over to the next year. And you have to answer yes to both questions about exclusive and regular use, not just one. The area of your home office must be used regularly and exclusively for business to deduct it.
