The advantage of filing this activity as a business is that you can easily report your expenses and reduce (or eliminate) your taxable income. As long as you have a loss, you don't pay self-employment taxes.
Reporting this as a hobby eliminates the possibility of self-employment taxes and any concern that you aren't pursuing a profitable business. However, the Tax Cuts and Jobs Act eliminated itemized miscellaneous deductions, including hobby losses, until after the 2025 tax year. (i.e., Hobby expenses are not deductible from 2018 to 2025.)
If you choose to report the 1099 income as a hobby, you will enter this as Miscellaneous Income that is reported on Form 1040 (the main federal tax form).
