Thank you and the others for this info!!! I thought I was going crazy. My plug-in purchase also took me over the TMT, preventing me from getting the charger credit. Can't blame TurboTax for implementing Federal tax law as it passed.
For the downloaded software version, the TMT result can be found by going to "Other Tax Situations," click on "update" for the AMT, then "edit," then answering the checkboxes, and then when it shows your AMT, click "show more."
