A couple of other tidbits - that are related and don't appear to be working right.
Yes refi’s are not being handled right in determining average loan balances hence the amount of deductible interest. But the problem runs deeper when a loan is handed off to a new servicer/investor which generates additional 1098s which TT then appears to recognize as new another loans. I believe the “loan acquisition date” is supposed to handle this, but I it appears this calculation is also erroneous right now.
Also the deductible points is far from clear on the TT u/i. If a loan involved upfront points, and the loan was partially used for upgrades to the home the u/i has no place to split out the portion of the points for those upgrades. One can do it in the Worksheets, but even there is is far from clear.
