dpad is not gone from a cooperative as they are on 2017 actually - it goes on a Schedule -
Schedule 1, Line 36. Add lines 23 through 35. The domestic production activities deduction (DPAD), for various trade or business activities conducted in the U.S., has been repealed for tax years beginning in 2018 or later. However, partners etc. of fiscal-year pass-through entities that have DPAD generated in a tax year beginning on or before Dec. 31, 2017 should enter their share of the entity’s DPAD on the dotted line next to line 36, identify it as “DPAD,” and include that amount on line 36.
