Just wanted to chime in here as I have almost the identical problem.....4 1098s, one was the original loan at the beginning of the year, two of which were refis and one was was a loan sale from one lender to another. I am also using TT premier. My mortgage interest was about 25K but the program kept coming up with only 14K allowed deductible. So, I followed the advice of one of the Expert posters in the thread above and entered the correct amount of the loan balance (box 2) on the very first 1098 entry (the program wont allow 0 on the first 1098 but will on subsequent 1098s). As suggested I then entered 0 in the loan balance box 2 on the remaining 1098s entered and the program now allows me the correct amount of deductible mortgage interest...approx 25K.
