the schedule C loss (gross income less expenses including depreciation ) will offset the W-2 wages.
but here's the thing. you will have a schedule c loss of $11,900 for 2019 and thus pay no Self-employment tax. However, this loss can not be carried over to 2020 to offset self employment income in that year so if you had no W-2 wages in 2020 and $11,900 in net se income you will pay se tax of about $1,700 in addition to regular income taxes.
