Deductions & credits

So finally what is the right way to go:

 

1. Should we follow the approach where we do enter two 1098's and for the first one we put 0 in line 2 OR

 

2. Follow this : https://ttlc.intuit.com/community/loans/help/what-do-i-do-if-i-have-multiple-1098s-from-refinancing-..., where we sum up box 1 and box 5 and put remaining values from first 1098. If this is the recommended approach then what is the answers for the questions asked in the original post which is

       1. Should I check the checkbox under Box1 "The interest amount I entered is different than what's on my               1098" since I add the amount from two 1098 forms.

        2.  Which lender name should I use? The orignal lender name or new lender name?
