I entered the contribution amount on line xa in form 502SU.  I thought it is up to $2,500 per contract but no matter how much I enter, the program subtract the whole amount instead of cutting the amount up to the limit.   Am I not supposed to enter the amount directly on line xa? And how do they know if I entered $5,000, that was for the one or two? I used supporting statement and put the names and the amount to show how many contracts. Am I doing it right?
