I did speak with live and got my answer. It was due to prior years' Alternative Minimum Tax and the "credit" that I had built up as a result. I didn't fully understand, and it was a new one for the live CPA as well, but it turns out that since I had been hit so hard with AMT in prior years, this now serves as a "credit" if I itemize. This credit can last up to 20 years! - Thanks
