Do not recall that I was asked to deduct my Arizona Income Tax of $2,546.00 I paid last year (2018) … Did I just miss that?

It might not matter if you missed it.  Do you think you will have enough to itemize this year?  This year the Standard Deduction will be doubling so many people will be switching to the Standard Deduction.  And there is a max 10,000 limit of State, local, property, and sales tax (SALT) deduction.  And you can only deduct Medical/Dental that's over 7.5% of your AGI.  And W2 job expenses have been suspended.
