Thanks so much for this solution, OMG! Are you kidding?!! WTF??? The only thing that I would add is that there was no 1098 entry in my forms list, even though I'd entered the data. I made them (and had 5! this year due to 3 refis and my broker selling the loan each time) using the "open forms", and then linking to the "worksheets" (also not in the list), but from there could also create a form. It was maddening. I mention it only because I'm not sure if the "Tax & Int Wks" sheet was even there before I did that, because I found this post after I spent 2 hours creating and recreating 1098 worksheets and forms (which didn't change the tax at all)... and then all I had to do was find the goldmine of a post and link to that obscure"Tax & Int Wks" form and change the checkbox?? Your description is exactly what happened to me. I got an error. Entered '0' in the box, and boom $7K of tax was added. Unbelievable, really. No way to take that zero back! Without this post, I'd still be searching. With that little checkbox, we got our $7K back!! I will definitely let turbotax help/support know if they EVER call me back. Their number is [phone number removed] if you're looking for it, but you may need to navigate their system to put in a request for help and get a case # (I did that and they recognized my phone number and associated it with the help request). Sorry for the long post, but a turbotax FU in the 1098 is kind of hard to believe. BTW, also using MacOS Premier.
