theres a worksheet in the prior year return that I print out for this...Ive got a cheat sheet at the office because I cant ever remember whats its called, I only have 2 or 3 clients that ever need this...I feel like it was someone (one of the regulars) in this group that lead me to it years ago... 

If I get a chance to dig it up at the office today, I'll post it.

If you select HELP while on one of the lines of Part V you can select complex recomputation of your XXXX income.   Or as the instructions say you can skip the process by selecting Recomputation not available.  

I cant find my cheat sheet (I must have left it in one of my clients folder), and it looks like I havent had anyone that needed it the past couple of years, so going by memory,  its called the Recovery Exclusion worksheet and you check a box in Part I for it to compute Parts II, III and IV and I think you look for the line in Part IV that has an asterisk next to it...thats the best I can do without having one right in front of me.

You can do it the old fashioned way.

Open up last year's return and/or make a copy of it.

Reduce the Sch A state tax by the amount refunded.

Then look at the new tax and AMT amounts.

Pardon me but this being Friday afternoon, and me being a Bourbon kind of guy, I couldn't help but feel obligated to add this:

CHEERS!

In the prior year's return, the AMT worksheet is in the LOAF, right after the State Refund Worksheet itself. 

List of All Forms.

>>>> "Recovery Excl" worksheet. Right after "State Tax Ded" worksheet.
