Business & farm

The sale of your business (Domain) is reported on Form 4797 Sales of Business Property which would then flow to Schedule D Capital Gains and Losses.

Go through your Schedule C Business. 

• You should have set up the Domain name as an asset when you set up your business. 
• If you didn't, you'll have to do that before you can "sell" the Domain name in TurboTax.
• Vanessa A is correct. Did you expense it?  If so, your cost basis would be $0.  Your cost basis is your cost minus depreciation.  So if you deducted that $800 in prior years, then you cannot deduct it from your current sale. 

To get to that section of TurboTax:

1. Open or continue your return
2. Search for schedule c and select the Jump to link in the search results
3. Edit the Asset Domain name.
4. When you get to the Tell Us More About This Asset/Large Purchase screen, select The item was sold, retired, stolen, destroyed, disposed of, converted to personal use, traded in, or given away (or it's no longer being used in this business for some other reason).
5. Continue with the onscreen interview until complete. 

To add an asset:

1. Type sch c in the search bar and click on Jump to sch c in the results box.
2. Either Edit or Review your business.
3. If you get to the First, select the expenses you know you had screen, check Assets and Continue. 
4. On the Add expenses  Check for others   Enter details screen, select Start next to Assets.
5. Continue with the onscreen interview to add your Domain name. If you expensed the $800, set up your basis as $0.00.
