For what it's worth, the desktop version of TT has a box you can check if your name is not listed first on the 1098. If you check the box, a page opens on which you enter the other taxpayer's info. Also, if the interest you claim is different than the amount on the 1098, TT takes you to a page on which you can enter a text explanation.
I don't know if the online version has these features.
