Taxpayer's SALT paid in 2020 (Sch A line 5d) was $50K.

Amount deducted was $10K (Sch A line5e).

Refund on the amended State return is $15K.  It's nontaxable because $15K is less than $40K (the excess SALT paid over the SALT deducted).  

I was hoping Lacerte would spit out a worksheet for that.  Am I lost or what?
