Turbo Tax and IRS Don't Agree

[Rich4]

I filed a form 1041 using Turbo Tax Business. I recently received a refund check from the IRS with an explanation that my calculations were in error and that because of this I am due a refund. What should I do if Turbo Tax and the IRS disagree with respect to the calculations? How do I contact Intuit about this problem?

Thank you for the response.  The issue specifically is that I received an IRS Notice CP133 along with a refund check. The IRS explanation for the refund was "We computed your tax using the Alternative Tax because it reduced your tax."  I am assuming that they are referring to the Alternative Minimum Tax because I'm not aware of any other Alternative Tax method.  I have a very simple return and can't see how there could be any confusion. My taxable income is well below the threshold for triggering the the AMT so that calculation should not even come into play.
