Do NOT be entering information in the Home Office section as a Sole Proprietor business.

For the K-1, are you a member of a Partnership?  Or are you a shareholder of a S-corporation?

I am a member of a partnership

 IF the Partnership Agreement requires you to pay for those expenses, then you can deduct it in the section where you enter your K-1.  There should be a check-box asking if you had expenses.

However, the program does not have a handy office form for that, so you will need to manually fill out Form 8829 to calculate what your office deduction will be.

Very helpful, thank you. Although in Turbo Tax it indicates the correct form is IRS publication 587.
