@Romo2 , I agree with @Mike9241 on that if the notice is fake, the contact number may be suspect for sure. However, and even with my error, any notice from the IRS these days is suspect. Thus :
1.please go through the notice to make sure that it makes sense ( compared to the return in question; then call the IRS general telephone number to make sure that this is a legitimate notice and that they really need this information from you.
2. thereafter, provide them the info they need to perform the desk audit.
Given what you have described so far of the situation, you should not have to spend monies getting a tax professional or the services of "Audit Defense.. " as mentioned by @Mike9241 . I say this because this is not a tax law issue at all -- just whether you are eligible for earlier paid AMT credit. Just documentation is all they need.
Sorry for the confusion
