You're lucky to get all your paperwork so early. I'm a TT user just like you and struggled a little bit until I figured out what was going on. I know you probably tried it a million times but go to step by step and check again that the screenshot I posted above has no values in any of those fields. That will trigger form 3468 investment credit. Once you remove the values you need to go back to forms, locate the form 3468, then click delete on the bottom of the page, then click save. That's what worked for me. If that doesn't work, create a backup, look around is it possible something else considered investment credit is also adding this form, start deleting things in step by step mode.
