I spent about 5 hours on this. Went through 3 support agents, it's 10:15PM, and no answer...I'm calling it a night. TurboTax, if you read this, I expect a refund. This is the second time in 5 years I've spent the better part of a day trouble shooting your software.
For me there were two issues:
1. Turbotax is calculating the CA adjustment assuming 1,100,000 in allowable principal. This would be correct if I had a Heloc up to the allowable limit of 100,000k. I don't. I (and several agents) have verified the questions multiple times (federal and state sections), redone state, re-entered mortgage interest to trick TT, deleted the CA home mortgage interest worksheet using tools/delete sheet and re-run the state multiple times...no dice.
2. In the process of doing #1, It sometimes deleted the ending balance screwing up the average principal calculation.
TT....if this many people have an issue, fix it. The way I found this thread was an agent suggesting this had the workaround. It does not, at least not for me.
