Tax cuts for USA Members

[USA only] Anyone here completed section 199A for declaring their QBI? Is that section mandatory or can I take the straight 20% deduction on my personal income tax return without that a section 199A line item?

Found the answer. For anyone that's curious -- pass through entity must report the QBI/199A in the "other" section of the K-1's that are issued using the new codes (V, U, etc.). The burden lies with the company to do the disclosure. Shareholders receiving the K-! can then take the appropriate 199A deduction.
