In 2019, Wilma Way's sole proprietorship, WW Bookstore, generated $120,000 net profit. In addition, Wilma recognized a $17,000 gain on the sale of business furniture and shelving, all of which was recaptured as ordinary income. The business checking account earned $960 interest income.

1. Which of these income items are subject to self-employment tax?
2. Compute Wilma's 2019 self-employment tax.
3. Compute Wilma's allowable QBI deduction, assuming $43,000 of W-2 wages and $90,000 unadjusted basis of tangible depreciable property. Further assume the overall taxable income limitation on QBI does not apply.
4. Compute Wilma's 2019 taxable income from her bookstore activity.

I need the solution for d. I am stuck and not able to get the answer. Thank you
