Retirement tax questions

Yes, I sched 3 line 3 has $2,000. Line 29 of the 1040 is $0.

 

I have a form 8863 Education Credits form part 2 filled out. Line 19 is $2,000. Line 31 of Part 3, Lifetime learning Credit is $10K.

 

Form 1099-Q line

16: 12,699

17: 9,268

18; 2,702  Where does this come from?

19: 1,972 Where does this come from?

20: 7,296 

23: 7,296

 

Form 1040 line 8

$7,296

 

This is my first year in graduate school. Am I eligible for the Lifetime Learning Credit? Is taking this somehow causing my 529 distribution to be counted as income?

Thx for the help.
