Additionally, you may want to do additional research on where to deduct the PTE taxes by the entity.  My understanding of why the states are creating these PTE filings, is to allow owners of pass-through entities the ability to pay the state level tax of the pass-thru at the ENTITY level.  

That way they can get the federal tax deduction for those state taxes at the entity level.  By putting the PTE tax deduction on line 12, code S of the Schedule K on the 1120S, you are effectively passing that tax deduction thru to the shareholder where it may be limited on Schedule A by the $10,000 cap.  That is the issue the PTE tax election was created to avoid.  

I have seen taxpayers taking these deduction on page 1 of the 1120S on line 12 as state taxes.
