I'm back! So select your "Business" tab in your program.
You should then see "Business Income and Expenses". (The screen is saying "Let's find some business deductions", but at the top you'll see Business Income and Expenses.
Once you click on that, you'll be given the options of "Walk me through everything" or "I'll choose what I work on".
Select "I'll choose what I work on".
This will open the screen with all info about your business income. Again, select Business Income and Expenses. You should be able to select your business from there, possibly the "Update" option. Once you locate the business you're wishing to dispose of, select it and the screen will open to all the info about your business. The first section should be "Business Profile". Once you choose to "Update" there, you'll see a screen where you can check all info about your business. Halfway down that screen, you'll see "Disposed of Business in Current Year". Select "Yes", and go from there.
Hope this helps.
