No Beyoncé album won Album of the Year at the 2014 Grammy ceremony.
The 56th Annual Grammy Awards took place on January 26, 2014. Beyoncé’s self-titled album had been released as a surprise in December 2013, so it was not eligible for that ceremony’s main album categories. Its Grammy recognition came at the following ceremony.
At the 2015 Grammys, Beyoncé received six nominations for Beyoncé and won three awards, including Best R&B Performance, Best R&B Song, and Best Surround Sound Album. Album of the Year went to Beck for Morning Phase at that ceremony.
This question concerns the award result, not whether Beyoncé was nominated or performed at a ceremony. Beyoncé later received Album of the Year nominations for Lemonade and Renaissance, but neither won that category. The distinction between nominations, wins, and eligibility years causes frequent confusion.
