As an S-corp, I'm filling out form 8936 and 8936 schedule A for a commercial EV. When I get to the final answer on Schedule A it says to transfer that number to form 8936 line 19. Then I'm supposed to put the credit on line 20 for an S-corp. Line 21 adds line 19 and 20 together. This makes no sense as it doubles the credit. Which line should I use to enter the result of Schedule A and which one should be 0?
