Sharing information I gather ...
Initially I presumed turbotax will update Utah income adjustments for those amounts in which under CA tax returns I declare $0 (i.e 100% utah income) or those amounts I declare it is 100% CA income. My presumption is wrong!
In Utah tax return TC40, it uses the federal AGI. And then you apply additions and subtractions to this federal AGI. Under turbotax Utah return and subtractions selection, select something that says income not accounted for by turbotax. Enter the adjustment amounts in "Equitable subtractions".
In the forms section, in TC 40A Part 2 Subtractions from income you will see Code 79 Equitable adjustments and the subtraction amounts to be applied to federal AGI.
