Since I contributed to 401k, is the AGI 1) shown in my W-2 Box 1 is the gross pay, $102300, minus $18500, $80k something or 2) calculated after the deductions:
Other adjustments used in calculating AGI include the following:
Then where is the MAGI shown? Or is it just a number I calculate and is not shown in w-2 either?
1) Unless your W-2 is your ONLY income and you have no 'above the line deductions' (the first two bulleted paragraphs that you listed), you can't figure out your AGI or your MAGI on your W-2. You need to look at your tax return (Line 37 for years 2017 and older).

I'm trying to determine my MAGI to determine if I am eligible for the American Education Credit or Lifelong Learning Credit. My gross income described in my other posts is $102000, and I maxed out my HSA, Roth IRA, and 401k for 2018.

Based on your LARGE number of questions (and your high income), you REALLY should be going to a tax professional. With so many things going on, you are likely missing out on some good tax advice.
