Where is the best place to enter the 2021 PTE payment amount, for S corporations, so they show up as a deduction for Fed but not State?  

I am thinking that the best place to enter it would be input screen 15 "Ordinary Deductions" on the line State Tax, but others at my firm feel that line should be designated for only the tax expense for the entity, not the PTE.  

Any feedback would be appreciated.
