you did not enter your 2020 year-end inventory value so Turbotax uses $0 resulting in a cost of goods sold equal to your beginning inventory. there are rules that apply to inventory. what happened to it in 2020? did you terminate your business? did you dispose of your inventory such as tossing it in the garbage? we can't tell you whether the 2020 loss is wrong or right unless we get further details on what happened. you should also be aware that you may be subject to the hobby loss rules which could allow the IRS to disallow the 2019 loss.
