Arizona form 321 - how to carry over credit from 2017 to 2018?

[Ak5234]

Arizona Form 321 allows up to $400 to qualified charitable organization. For 2017, my taxes were less than $400, and I would like to carry over the difference to 2018. What line does that go on for Form 321?  Or will TT just know for next year? It is unclear to me thank you.

Turbo Tax calculates your carry-over credits to your future year's federal and state returns automatically when your credit is one which Turbo Tax supports.

There is also a statement in the supplemental pages of your return which will summarize any federal or state carry-overs that you have remaining. when you go to print your return, print all forms and statements to see a copy of your schedule of carry-overs.
