If i receive a K-1 from a business venture and also receive a W-2 from them, can I take a Home office deduction if all my business is from my house?

See https://turbotax.intuit.com/tax-tips/jobs-and-career/tax-tips-for-employees-who-work-at-home/L5AinJbgn

what type of entity/ an s_corp or partnership? if so, there are rules for an S_Corp shareholder/ S-corp to take the HO deduction or if you were an employee of a partnership that later in the year became a partner and your w-2 was discontinued, then you may be entitled to a HO deduction for the portion of the year you were only a partner (really unclear), if this is your situation again there are specific rules that must be followed. 

To clarify I am an owner in the K-1 Venture.  It  also pays me wages.  I work at home because there is not another office to work from.  So this work to help the promote and carry on the functions of the K-1 business cannot be deducted on my tax return?
