Business & farm

Just blindly following the walkthrough didn't lead me to it.  So I kept hitting "Visit All" but it didn't hit me that one of the walkthroughs questions had depreciation.  It's not until I read through each thing under "Visit All" that I noticed "Assets and depreciation".  Just click on the "Update" button next to it and say "Yes" and you'll be walked through to enter the depreciation for the start-up cost and it'll automatically calculate it for you for 180 months.

It's under Business Expense > Assets and depreciation
