Deductions & credits

#1. I was just thinking if I did something wrong. I don't think I entered anything wrong.

#2. Yes. I am stuck trying to find the amounts for the highlighted boxes:

I am looking through my 2018 return but cannot find these two amounts. The only places that has line 45 and 46 mentioned looks like this:

As you can see, they don't mention anything about "Alternative Minimum Tax (AMT) or Excessive advance premium tax credit repayment. I don't know where else to look for this information if this is not the right place.

Thanks.
