For a sole proprietorship, if I registered it in 2022, incurred expenses, but did not make a sale, should I select both "started work in 2022" and "stopped work in 2022?"

If you didn't have any sales, it is possible that you weren't technically in business, in which case you shouldn't enter the business on your tax return in the current year. If you weren't open for business, then the costs you incurred would likely be considered start-up expenses, which you would start to deduct in the following year when you opened for business.

If you mean you started the business but didn't have any sales and then you closed it down, you would also not enter it on your tax return since you were never in business. If your expenses were material and you expended a serious amount of time and efffort on the business formation but never opened for business and then abandoned the project, you may be able to deduct the expenses as a loss on an investment, but you wouldn't enter it as a business in TurboTax.

If you were open for business but just didn't sell anything, you could enter it as a business and then report it as being shut down in the current year. But this might attract unwanted attention from the IRS, as it is unusual to have a business that didn't generate any revenue.

You would enter an investment loss in TurboTax by following these steps:

1. Choose the Federal option on your left menu bar
2. Choose Wages & Income
3. Choose the Investments and Savings (1099-B, 1099-INT, 1099-DIV, 1099-K, Crypto) option
4. Choose Add investments
5. Choose the Stocks, Bonds, Mutual Funds option and follow the instructions
6. Enter your business expenses as the cost of the investment and $0 for the sale proceeds
