Yes, it sounds like you didn't use use AMTFTC in prior tax years. But it does sound like you got the full foreign tax credit. The AMT foreign tax credit is similar to the foreign tax credit for regular income tax purposes, except that it is limited to the foreign tax on foreign source alternative minimum taxable income (AMTI) instead of foreign tax on regular taxable income. Without seeing your returns that were prepared by your CPA firm, we can't be sure if you were subject to AMT or not, but it sounds like you were not. If you only used Form 1116 and not 116 AMT, it would indicate that you weren't limited to the full foreign tax credit because of AMT.
