I tried both methods with a refi between $400-700k in NY: the 'add everything' or 'manually use forms' mode. Both give the same results.
However, the 'add everything' instructions are unclear. They recommend to use the original lender, so that means you need to provide the old bank and the original close date? Doesn't make sense.
I read above that TurboTax doesn't "support" manual edits, but they need to make an exception here. I am simply not comfortable by providing incorrect tax data to the IRS by simply adding numbers.
