Co-pilot helped me find the answer! First, you find your AGI which should be listed on your Turbo Tax tax return home page. Then you add any numbers in 1040 line 2a and Schedule 1 line 20 (aside from that, it's just if you have student debt interest or foreign income interest ...which I had neither of ...but if you do, I found Co-pilot to be helpful if you need to find those lines on the return:-)
