I'll echo the other recent post - this is not fixed. If you refinanced, and follow the new instructions (combine the interest and enter only one 1098), the interest amount is still not correct unless your refinanced loan is for the exact amount of the previous loan's payoff. If you financed the closing costs, then the method described by TT will deduct too much interest. And if you try to deduct any points, then it throws everything off.
If you have a second home loan, then it is all screwed up.
I could go into detail, but I'm not. TT - do your research and do your job. As someone said in an earlier post, this ain't rocket science. All you need to do is mimic the calculations as shown in Pub 936, which specifically says that you cannot use the first and last balance method if you prepaid more than 1 month's principal during the year. This includes refinancing.
It is hard to believe that these IRS rules went into effect in 2017, yet it seems that TT never fixed it.
