Deductions & credits

To make things more confusing, I did not itemize last year (2018), but I MIGHT itemize my 2019 taxes (just too soon to tell).  

 

As I recall, you normally reduce what you claim as property tax deduction by this credit (in the details for my prop tax in TT).  Ignoring, of course, that the Trump tax increase means that I can only deduct the first $10k of my state income and local property tax, which are way above $10k.  So if I don't itemize, what do I do in TT about this credit?  If I do itemize, I'd think that given that I have at least $20k in total SALT that taking it off my prop tax total will have no effect.  

 

Thanks,
