How can I see if I have claimed the education credit?

If you mean the American Opportunity Tax Credit---it will be on line 29 of your Form 1040.

The AOTC comes in two pieces. Look at form 8863.  From there the numbers go to Schedule 3, then to lines 29 and 20 on form 1040.  The refundable portion is on line 29 and the 2nd piece on line 20 (from schedule 3). 

The education credits are calculated on form 8863. The refundable part of the American Opportunity Credit goes on form 1040 line 29 and the nonrefundable part of the AOC or the Lifetime Learning Credit( whichever you qualify for) goes on SCHEDULE 3 (Form 1040) line 19, then the total of nonrefundable credits goes on form 1040 line 20.
