In my case we elected the Simplified AMT limit in a prior year and apparently once you do that you can't change without IRS approval.  The election is made on Form 6251 below line 7. With this return there is more than $300 in FTC.  I'm going to file a paper return with Form 8948 stating that ProSeries says its not eligible for electronic filing because of the Simplified AMT FTC limit.  

Thanks for responding.
