Mortgage Interest

I recieved two 1098 forms. One from my co-op and the other from my mortgage company. I also recieved a letter from the coops accountant. The letter has the per share info.

 

Box 1 on both forms has a different amount for mortgage interest and the letter has  $2.85 per share for mortgage interest and $6.57 for real estate taxes.

 

Which of the three numbers do I use or how do I figure it out. Please explain. Thank you.
